This file documents the changes made to GeoStudio 2007 since the initial release (version 7.00). The numbers in parentheses after some items refer to a Knowledge Base article with more information. These Knowledge Base articles may be found by visiting the GEO-SLOPE web site at http://www.geo-slope.com.
· A bug was fixed which prevented GeoStudio from launching SOLVE when working with a file with a UNC path.
· A bug was fixed which could cause GeoStudio to crash when adding or deleting a region.
· Setup no longer forces you to uninstall first.
· Any contours being displayed in DEFINE will now be updated when the initial condition time step is changed in KeyIn Analyses.
· When the “(all)” time step is selected, contours (in DEFINE) will reflect values at the last step.
· A bug was fixed which could cause Verify to report mesh incompatibility in certain cases when upgrading older files, because the mesh would not be regenerated.
· When used with the /log command line switch, GeoStudio now logs additional information such as its version, what file is being opened, what command line switches are being used, and all messages reported by Verify (when used in conjunction with /verify or /solve).
· A bug was fixed which could cause small stray lines to appear (apparently randomly) when contouring some data.
· The /clean command line switch now attempts to repair corrupted data files.
· Added a /verify command line switch to run Tools Verify for the selected analyses.
· A bug was fixed which caused meshing constraints on surface regions to be lost when using the /clean command line option.
· A bug was fixed in Set Units and Scale that could introduce small variations in the values typed in after closing and re-opening the dialog.
· A bug was fixed which would occasionally cause GeoStudio to crash while shutting down.
· An analysis’ elapsed time displayed in the tree view in KeyIn Analyses now displays the same number of significant digits as in the Time tab.
· In KeyIn Spatial Functions, if the grid is on and you drag a point, the point will now snap to the grid.
· A bug was fixed which could lose images when importing from a version 5 file.
· GeoStudio can now handle the case where more than one .xml file exists in the same directory.
· A bug was fixed which could fail to upgrade some sketch text when opening a version 7.0x file (particularly when the sketch text contained units).
· A bug was fixed with KeyIn Spatial Functions which could allow more than one Spatial Function dialog to be displayed at once.
· When copying a list of function points, the “missing” points at the bottom of the list are no longer copied.
· A bug was fixed which prevented the thumbnail from being properly generated for a file that linked to a picture that no longer existed.
· When printing a project that includes a picture that no longer exists, the error message about the missing picture is no longer included in the printout.
· Tools Verify will report a warning if a child analysis’s start time is earlier than its parent’s end time, if both analyses are of the same kind. In such cases CONTOUR will not be able to display results (such as graphs and movies) across both analyses, only for the current analysis. Additionally a bug was fixed in CONTOUR that would prevent it from displaying all the time steps of even the current analysis in such cases.
· Fixed KeyIn Analyses so it closes any other dialog boxes.
· The behavior of graphs with custom ranges was improved to give nicer numbers on the axes.
· A bug was fixed which caused SLOPE/W SOLVE to crash if the Description field in the file was longer than 275 characters.
· Changes were made to the algorithm for removing thin slip surface slices. In KeyIn Analyses, on the Advanced tab, there is no longer a “Minimum slice width” field. Instead SLOPE/W removes slices that are substantially smaller than their neighbor, while avoiding removing “critical” slices such as those that intersect piezometric line points or ground surface points. This avoids several problems that have been reported, especially when modeling vertical walls, such as a higher FOS being computed for the optimized slip surface; portions of slices being missing; and a different FOS being reported in the SOLVE window vs. in CONTOUR.
· The “factor of safety vs. lambda” graph can now be displayed even for slip surfaces with a 998 error code.
· The “Allow Passive Mode” feature was renamed to “Use Passive Mode” to better reflect its behavior.
· SLOPE/W now ensures the slip surface is in the right direction even when the Use Passive Mode option is checked.
· A bug was fixed which could result in different factors of safety being computed on different computers or operating systems when using the Auto-Locate slip surface method and slip surface limits that were not at the end of the ground surface line.
· A bug was fixed which would cause CONTOUR to display the wrong grid of centers when doing a transient analysis with optimization.
· A bug was fixed in displaying ponding shading. When using the “Piezometric Line with Ru” or “with B-bar” in KeyIn Analyses and with the “Apply Phreatic Correction” option turned on, and if the piezometric line was above the ground surface and contained a vertical segment, the shading would not be displayed.
· When using the “Apply Phreatic Correction” option (with “Piezometric Line with Ru” or “Piezometric Line with B-bar”), phreatic correction is now ONLY applied to portions of the piezometric line that are below the ground surface. No correction is applied above the ground surface.
· A bug was fixed in computing overburden stress, to include weight from surface ponded water. The overburden stress is used in the S=f(overburden) model and the bond resistance calculation for a fabric load when a Phi is used.
· A bug was fixed in Draw/KeyIn Slip Surface Entry and Exit Range, which could cause the range symbols to be displayed above the ground surface line.
· View Object Information no longer allows selecting lines in SLOPE/W, as lines do not have any meaningful information (only x,y coordinates, which can be reached through regions). This helps select thin regions without having to zoom way in.
· A bug was fixed in the factor of safety calculations when doing multiple time steps with optimization.
· A bug was fixed which could cause the factor of safety displayed on the main drawing to be different from the one displayed in View Slice Information, when the last slice is on a vertical edge and the piezometric line is vertical.
· A bug was fixed in the Entry and Exit slip surface with Radius, that could over-constrain the slip surface generation and thus crash SOLVE or generate an incorrect slip surface.
· Rather than checking that the slip surface exit angle be no more than 45 degrees, SLOPE/W now checks that the M-alpha value is no smaller than 0.01. This is a better check since it considers both the exit angle and the material frictional angle.
· A bug was fixed in displaying entry/exit ranges that include a vertical line.
· A bug was fixed in sketch text which could cause GeoStudio to crash when displaying sketch text fields related to the current slip surface, then selecting a different slip surface.
· A bug was fixed with reinforcements, line loads and pressure lines in slope finite element analyses. These objects are no longer displayed when the analysis uses a FE method, as they are ignored by SOLVE.
· In Draw Reinforcement, if you click twice on the same point, the second click is now ignored rather than displaying an error message. This also fixes a bug where the error message would be displayed incorrectly if you clicked on the drawing after editing a value in the dialog box.
· A bug was fixed in CONTOUR which in some cases prevented switching back to the optimized slip surface after switching away from it.
· A bug was fixed with vertical slopes and saturated tension cracks, which could apply the water force to the wrong slice.
· A bug was fixed in thermal conductivity function estimation when using imperial units.
· A bug was fixed in KeyIn Particles. Previously particles created in KeyIn Particles would never be displayed or used by SOLVE.
· A bug was fixed deleting particles. If you deleted a particle using Modify Objects, in some cases it would still appear in the list in KeyIn Particles (though it would still not be displayed or used by SOLVE).
· Particles are no longer required to be on mesh nodes.
· A bug was fixed which could cause Tools Verify to report errors about particles even for analyses that were not particle-tracking.
· The Engineering Books have been updated with discussion on the new features and detailed examples.
· Example files, problem descriptions, and tutorial movies are now installed with GeoStudio and can be searched from the new GeoStudio Start Page. When you open one of the examples, it will be opened in Start Page view, allowing you to see a thumbnail view of the drawing and select one of the analyses to view in more detail.
· When displaying a folder of GeoStudio data files in Windows Explorer, different icons will be displayed for files created with GeoStudio 2007 and previous versions of GeoStudio. When displaying the files in Thumbnail view, a thumbnail picture of the file geometry is displayed for files saved with GeoStudio 2007 v7.1.
· View Report now generates reports for all products, allowing you to view a summary of any analysis definition. You can choose View Report from either DEFINE or CONTOUR.
· Draw Contours now lets you store sets of parameter values to contour. Each Contour that you create can have different parameters, contour ranges or shading options, and will be visible in all analyses where the contour parameter is defined.
· A new Contour toolbar lets you quickly select the Contour parameters to display.
· Sketch Text fields have been improved in several ways. You can now choose fields to display various analysis results and other values in CONTOUR. The fields have been reorganized to make them easier to find; only fields that exist in the current analysis are displayed, and they are shown using titles rather than the actual field names. Any fields that cannot be resolved (e.g., due to an incorrect field name or the field not applying to the analysis) are not displayed in the GeoStudio window. Also, the Materials table only includes materials in the current analysis.
· Sketch text now has an option to only be shown for a specific analysis. This allows you to hide irrelevant text when in other analyses.
· The Help menu now contains commands to quickly access the Engineering books, Example data files, and Tutorial movies.
· GeoStudio can now be run from the command line in order to automatically open, save, and solve many data files.
· Add-Ins have been improved in several ways. Add-Ins can now be written to use custom data parameters that read data from memory or write data to the analysis results files for later contouring or graphing. Add-Ins can project nodal data to any x,y location. The Add-In can access data from any solved GeoStudio analysis in the same file. Add-Ins now support additional field types including string, unsigned and int. When entering values for Add-Ins, you can now use the Tab or Enter key to accept the current value and immediately move on to the next one. In a transient analysis, Add-Ins can know the time step in an externally referenced file. Finally, if an Add-In returns an error (i.e., throws an exception) during solving, the error message is displayed in SOLVE.
· When “Parent Analysis” is selected for an initial condition, you can also select any time step from the parent analysis. Previously you had to choose Other GeoStudio Analysis if you wanted any time step other than the last one.
· When you open a data file and cannot get a valid license, you can now optionally open the file in Viewer mode.
· You now have the option of displaying the region label as a material name. The display setting is available in View Preferences.
· In View Result Information, if you copy, print or export the data, rows and columns are swapped from what View Result Information shows, to better fit those media.
· GeoStudio is now faster when switching between analyses or views.
· When opening v6 files, any objects (such as functions) that have duplicate names are now renamed automatically.
· If you close GeoStudio while a file is open and SOLVE is running, SOLVE will now exit when it is done.
· Verify now reports an error when two regions overlap each other.
· Verify now reports an error when material functions are undefined.
· Object selection in View Object Information has been improved to more accurately reflect the current View Preferences.
· By default, the “Material Boundaries” view preference is now off.
· Sketch Pictures can now re-link to a picture that has moved, and any resizing that was done previously is now retained.
· When running a second instance of GeoStudio or SOLVE, the second instance no longer opens on top of the first.
· A bug was fixed where clicking on the Engineering book links in the Online Help wouldn’t open the file.
· A bug was fixed where deleting a function could sometimes result in GeoStudio not being able to open the data file the next time.
· A bug was fixed where using an extremely large scale in Set Units and Scale would cause GeoStudio to crash.
· A bug was fixed where generating contours in an extremely large mesh (e.g., 100,000 elements) could cause GeoStudio to crash.
· A bug was fixed which could cause an analysis to be reported as “solution out of date” even when no changes were made.
· Some edit boxes wouldn’t let you type further than the width of the edit box, such as the Axis Title in a graph.
· A bug was fixed in estimating hydraulic conductivity functions that could produce incorrect values in some cases.
· A bug was fixed that could cause GeoStudio to crash after deleting a function and saving, which would prevent you from re-opening that file.
· A bug was fixed in KeyIn Points, where you could not change a point coordinate if the new coordinate was very close to the original value.
· A bug was fixed where some units were displayed incorrectly in a few dialog boxes. This bug only affected the dialog box display, not the results.
· A bug was fixed which could cause the red “selection” lines around selected regions or lines to be painted in the wrong location.
· A bug was fixed which sometimes caused GeoStudio to crash when clicking on the View Assigned button in some KeyIn or Draw dialog boxes.
· A bug was fixed that prevented assigning a material to the outside of a circular region.
· A bug was fixed where copying the drawing and pasting it into another application, such as Microsoft Word, resulted in the thick lines (e.g., the PWP line) displaying too thick.
· A bug was fixed where in a few rare cases, clicking Undo would not undo the previous action.
· Initial conditions can now be defined spatially across the geometry as a function of x and y. Supported spatial initial conditions include PWP, temperature, air pressure, concentration, and gas concentration.
· Draw Contours lets you view the defined parameter values that SOLVE will use for certain initial conditions.
· A new Face boundary condition lets boundary conditions be applied to regions as flux per unit volume.
· Changing the boundary condition type now assigns a different default color. This allows you to distinguish between primary, flux and unit flux boundary types.
· The finite element unstructured meshing now produces smoother-looking meshes in some cases.
· It is now possible to remove material associations in the Draw Surface Layer Materials command.
· A bug was fixed that caused SOLVE to crash when computing the flux values for a sloping flux section that was also parallel to an element edge.
· A bug was fixed that caused Draw Flow Paths to display an error when the flow path encountered a null element.
· A bug was fixed sometimes didn’t allow flux sections to intersect with a node in the finite element mesh.
· A bug was fixed that prevented some hydraulic boundary condition symbols from being displayed on the drawing.
· SLOPE/W now includes a new Spatial Mohr Coulomb material model, which allows unit weight, cohesion, and phi to vary spatially across the geometry as a function of x and y. Additionally, the Shear/Normal Fn and S=f(overburden) material models now allow unit weight to be defined as a spatial function.
· SLOPE/W now automatically applies the weight of ponded water wherever there is excess PWP on the ground surface. The excess PWP is displayed as blue arrows and a shaded blue region above the ground surface.
· A new Draw Contours command in DEFINE lets you view the defined parameter values that SOLVE will use for pore-water pressure, cohesion, phi, and unit weight.
· The No Strength material model has been removed from SLOPE/W. This model is no longer required to model ponded water, since SLOPE/W now computes the ponded water weight automatically. In addition, the Draw Surcharge Loads command can be used to model no-strength materials with different unit weights. (KB717)
· Surcharge loads can now defined as positive or negative values, with the option to apply the load in the normal direction. This allows you to adjust the effect of the ponded water weight.
· The ponded water weight is now applied normally to each slice, rather than as a single horizontal force acting on the first or last slice.
· A collapsed surface angle can now be used with the Mohr-Coulomb model when the “Use steady-state strength when liquefied” option is selected. If a Phi angle is also used for the material, then Phi must be greater than the collapse surface angle.
· Pressure lines are now referred to as “Surcharge Loads”, and line loads are now referred to as “Point Loads”.
· Modeling of steep rock slopes has been improved when using the Block slip surface method. When drawing the blocks, the order that you click the points is now preserved, which allows you to generate steep parallel slip surfaces in conjunction with the “no crossing” option on the block slip surfaces.
· You can now specify a wider range of projection angles for slip surface blocks, the slip surface radius, and tension cracks.
· SLOPE/W now supports the View Movie command to let you make movies of your transient stability analysis results.
· Pore-water pressure (e.g., a piezometric line) can now be displayed as a thick or thin line.
· The unit weight of water in a tension crack is now updated whenever the global unit weight of water is changed in Set Units and Scale.
· The S=f(datum) material model now allows the datum value to be negative.
· You can now optionally cap the suction for pressures above a piezometric line. The Cap Suction option no longer applies to the entire analysis.
· Drawing point loads or surcharge loads now snaps to existing region lines or points, allowing you to draw a point load right on the ground surface rather than having to make sure it's below the ground surface.
· Verify now checks that the piezometric lines used in a Rapid Drawdown analysis are valid and do not cross. Also, the order of the piezometric lines is no longer important in a Rapid Drawdown analysis; the top line will always be chosen as the starting condition.
· SLOPE/W now computes the slice height from the mid-point of the straight edge of the slice base. For a circular slip surface, SLOPE/W used to compute the height from the arc underneath the slice base.
· Tools Verify now checks that surcharge loads do not lie under the ground surface line.
· Performance when displaying safety maps has been improved.
· Draw Graph now supports plotting m-Alpha.
· The tension crack line is no longer displayed if the analysis does not use it.
· SOLVE now displays an error if an attempt is made to read stresses from an excavated element in another analysis.
· A bug was fixed that could cause SOLVE to crash when there are invalid entry and exit definitions with vertical edges. Now such invalid slip surfaces are given a 992 error code.
· A bug was fixed in the pore-water pressure calculation when a piezometric line was used that contained a vertical edge.
· A bug was fixed calculating the points on an adjusted piezometric line when there is also a vertical slip surface line.
· A bug was fixed where creating a reinforcement and changing its type sometimes resulted in old values being used in SOLVE. For example, creating a Fabric and then changing the type to a Nail could result in some of the old Fabric values being used.
· A bug was fixed where SOLVE could compute incorrect values when using finite element computed stresses or pore-water pressures from an external analysis that has a different mesh than the one stored in the file with the SLOPE/W analysis.
· A bug was fixed where GeoStudio would crash in Modify Objects when selecting a partially defined reinforcement object.
· A bug was fixed where GeoStudio could crash while running Verify after deleting an analysis that used to use a Tension Crack Line.
· A bug was fixed where importing a v6 SLOPE/W file sometimes did not properly import the “Add Weight” option (for B-bar) or “Include in PWP” option (for Ru) in KeyIn Piezometric Lines.
· A bug was fixed where SOLVE would sometimes crash while solving a Newmark analysis.
· A bug was fixed where in a rare case using piezometric lines, B-bar value, and the “Add weight” option, two different factors of safety could be obtained for the same slip surface.
· A bug was fixed where SOLVE could potentially crash while computing reinforcement loads.
· A bug was fixed that caused View Slice Information to be disabled in some cases even when valid slip surfaces were computed.
· A bug was fixed where you were unable to change the PWP View Preference when the initial pore-water pressure was being obtained from an external or parent analysis.
· A bug was fixed the water table was not displayed in SLOPE/W CONTOUR when the initial pore-water pressure was being obtained from an external analysis.
· A bug was fixed where used File New to create a New analysis would result in some of the PWP options not being displayed in KeyIn Analyses.
· A bug was fixed in KeyIn Analyses where the slip surface tab would be blank when switching the analysis type to or from QUAKE/W Newmark Deformation.
· A bug was fixed involving pore-water pressures computed for probabilistic and sensitivity analyses.
· A bug was fixed in SLOPE/W CONTOUR so it will no longer paint the water table from a finite element analysis in regions that were excavated in the finite element analysis.
· A bug was fixed where the Draw Sensitivity graph showed incorrect labels when displaying results for different piezometric lines.
· A bug was fixed in SEEP/W when modeling freezing together with flowing water. When using imperial units, the water velocity would not shut down in the frozen ground.
· A bug was fixed where SOLVE could crash in a Convective Heat Transfer analysis when TEMP/W SOLVE had reached its maximum number of iterations.
· A bug was fixed where SOLVE could crash if there were material property functions that were undefined.
· A bug was fixed in SOLVE where in certain cases that used a Head vs. Time boundary function on a slope with the Review option enabled, the boundary condition above the seepage point would get set to zero, thus letting flow into the mesh when it should not.
· A new Dynamic Deformation analysis type lets you analyze post earthquake transient plastic deformation. Use results from a QUAKE/W dynamic analysis (or SIGMA/W analysis) to compute the deformations due to nodal forces generated from the incremental element stresses.
· You can now view the liquefaction zone in SIGMA/W CONTOUR.
· In a Coupled Stress/PWP analysis, you can now specify the pressure-load response ratio if the default 100% is not desired.
· A Collapse Surface Angle can now be specified when the “Use steady-state strength when liquefied” option is selected.
· KeyIn Materials in SIGMA/W now allows you to enter negative values for unit weight.
· SOLVE now computes total head inside a total stress material as a “missing” value. This means that PWP contours will not be generated within these materials.
· A bug was fixed where in some cases, SOLVE could crash when performing a coupled consolidation analysis.
· A bug was fixed when using the Hyperbolic material model in staged construction, where the initial load path was not always set to the correct value in SOLVE.
· A bug was fixed when using both material activation pressures and an initial water table, where the values of both were being averaged instead of being used individually.
· A bug was fixed where SOLVE could get a stress value from a null element.
· When computing liquefaction, the stress state must now be between critical and collapse states, not just above critical state as it was previously. The stress state must move into the collapse zone in order to trigger liquefaction.
· KeyIn Materials in QUAKE/W now allows you to enter negative values for unit weight.
· Verify now checks that both Gmax and Damping Ratio functions are properly defined.
· A bug was fixed in importing earthquake records with more than 10 columns.
· A bug was fixed which would cause GeoStudio to crash when using Edit Copy from the menu after clicking the View button in KeyIn Earthquake Records.
· CTRAN/W can now read pore-water pressures computed by a SIGMA/W Coupled Stress/PWP analysis.
· CTRAN/W can now generate graph of the solution convergence data.
· A bug was fixed where CTRAN/W sometimes treated a region as having no assigned material when it actually had one assigned.
· SOLVE now saves intermediate results more frequently, such that if SOLVE is interrupted (e.g., by a power failure), it can continue where it left off.
· Computing ice contents is now based on the unfrozen water and air contents, which should result in smoother ice content profiles.
· When no initial ice content is available in an initial condition, the ice content is now set to 0.
· The Draw Graph command now uses the Surface Region Nodes selection to graph ground surface nodes.
· A bug was fixed in VADOSE/W when modeling freezing together with flowing water where the water velocity would not shut down in the frozen ground.
· A bug was fixed where importing climate data set the date to the current date, rather than the one in the climate data record.
· A bug was fixed in CONTOUR where for a steady-state analysis, incorrect volumetric water content values were sometimes displayed, even though the values used to compute the results were correct.
· A bug was fixed where GeoStudio would sometimes crash in KeyIn Climate Data while deleting data.
Version 7.04 was only released as a beta version. However, the following changes made in Version 7.04 have been officially released in Version 7.1.
· Network licenses may now be “borrowable”. A separate utility called GeoBorrow can be installed on a computer and used along with a borrowable network license to temporarily borrow network licenses so as to use them offline.
· Speed improvements were made to many dialog boxes. In particular, KeyIn Analyses and Draw Mesh Properties are noticeably faster, though other dialogs are affected by this change as well.
· Sketch Text has been changed to make it easier to label materials. The Materials tab (in the Fields dialog) now makes you select a region or line rather than a material, then automatically uses the material assigned to that region or line. The result is that as you change analyses or apply new materials, the text label updates accordingly.
· If an invalid field is used in Sketch Text, an error message will only be displayed when in the Sketch Text (or Modify Sketch Text) mode. In all other cases the text will simply not appear. This helps in situations with several analyses when some text only applies to one analysis—in all other analyses it will simply not appear.
· View Movie can now be used to create a movie of only one part of the geometry, much like Copy Selected or Print Selected.
· The Analyses tree view in the toolbar will now size itself large enough to display all analyses.
· When using data from an external file, SOLVE now ensures the other file was created with the same version of GeoStudio as the file being solved.
· When a file is closed in GeoStudio, any SOLVE windows that GeoStudio launched are also closed.
· When a material model changes, the ground surface line is recalculated. This only affects the display, not the results.
· The View Assigned dialog box now defaults to selecting the same item that was selected in the dialog box that launched it.
· Draw Lines now allows a new line to be started by clicking on an existing line. Previously clicking a line would select it.
· It is now easier to draw some objects such as regions, lines and entry & exit slip surfaces when the grid is on, due to changes in how the mouse snaps to existing objects.
· The “Auto-Fit Page” option in Modify Objects is now saved with the file.
· Modify Objects will now snap regions or lines to the grid. Previously it snapped the mouse cursor to the grid, which made it difficult to move regions or lines with the grid on.
· Draw Regions, Modify Objects and Verify will now report an error if they detect overlapping circular regions.
· The View Object Information tree view now retains the state of collapsed or expanded sections as you select different objects.
· DXF output now uses blocks and block references, and supports Mtext.
· Units have been added to some dialog boxes and have been corrected in a few other dialog boxes.
· Dialog box control layout has been improved when you resize the dialog box.
· A bug was fixed in selecting an external analysis in KeyIn Analyses (such as for initial conditions). If the file that was previously selected no longer existed, it was impossible to make another selection.
· A bug was fixed which could cause GeoStudio to crash when pasting points into functions.
· A bug was fixed which prevented GeoStudio from recognizing some USB keys when more than one key was attached.
· A bug was fixed which prevented GeoStudio from freeing up some of its internal memory and resources, which could cause your computer to become unresponsive if GeoStudio is left running for a long time.
· A bug was fixed which could cause GeoStudio to crash when cloning an analysis immediately after opening a v6 file.
· A bug was fixed which could cause GeoStudio to crash when switching to CONTOUR after opening a file with a very long name.
· A bug was fixed which could crash GeoStudio when canceling closing a file.
· A bug was fixed related to initial conditions. If the initial condition option was set in an analysis type that uses it, then the analysis was switched to a type that did not, DEFINE would still use the initial condition for display purposes, such as displaying body load hatching. This bug did not affect results.
· A bug was fixed which tied the animation’s duration (using View Movie) to the analysis’ time units, so the default duration of a movie could be days long. Now the animation’s duration is always seconds.
· A bug was fixed in generating time steps which could generate too few steps or include some unexpected increment times when dealing with thousands of time steps.
· A bug was fixed which could cause the default element width to be miscalculated after changes in Set Units and Scale.
· A bug was fixed which could occasionally cause all the product icons on the Start Page to appear to be disabled even when a valid license is present.
· A bug was fixed which could cause the ‘*’ to appear in the title bar indicating the file needs to be saved even after saving the file.
· A bug was fixed in Sketch Pictures which could cause the mouse cursor to disappear under certain circumstances.
· A bug was fixed which could display the wrong mouse cursor after some “temporary” modes like Zoom In.
· A bug was fixed which could cause an analysis to be reported as “solution out of date” even when no changes were made.
· A bug was fixed which could cause the ‘*’ to appear in the title bar indicating the file needs to be saved even if no file was open.
· A bug was fixed which could cause Zoom Objects to zoom way too far out when sketch text exists with blank lines.
· A bug was fixed which caused some windows to open in the same location every time GeoStudio was run, rather than remembering how they were last positioned and sized.
· A bug was fixed in DXF import where rotated ellipses were being imported with an incorrect rotation angle.
· A bug was fixed in Draw Graph which could cause GeoStudio to crash under certain conditions.
· A bug was fixed in File Print which would truncate large values for custom extents.
· A bug was fixed in Draw Graph to improve the presentation of numbers displayed along the axes.
· Improvements have been made to Plan View, including a Generate button in Set Units and Scale, removing the Element Thickness field in Draw Mesh Properties, storing additional Plan View data to file, and supporting Plan View in CTRAN/W and TEMP/W.
· An “All Boundary Conditions” option is now available in View Preferences, Draw Boundary Conditions and KeyIn Boundary Conditions to display and work with all BCs simultaneously.
· You can now include cumulative data (such as flow or displacement) from initial condition analyses to better chain a series of analyses. See the “exclude cumulative values from previous analyses” checkbox in KeyIn Analyses.
· In Draw Boundary Conditions, you must now specify if you are drawing the BC on a point, line or region.
· Student and Basic licenses will now always use the direct solver option.
· When a boundary condition uses an Add-In function, it is allowed to be applied to any geometry. (Rules such as allowing unit flux BCs only on lines are ignored.)
· Units are now displayed in the Action field for boundary conditions.
· A bug was fixed which could cause GeoStudio to crash when saving a file after deleting a boundary condition.
· A bug was fixed which could cause GeoStudio to stop responding in View Information when selecting a region with a material that had certain kinds of invalid functions.
· A bug was fixed which could mark nodes along the edge of a tunnel sitting inside a surface region as surface nodes. This bug affected results generated by SOLVE as well as graphing results when selecting nodes marked as surface nodes.
· A bug was fixed in View Result Information when values were missing.
· A bug was fixed in View Result Information to better size the columns.
· A bug was fixed which could display a very small but non-zero value as a label on contour lines when it should be zero.
· A bug was fixed so secondary nodes would be deleted when an infinite region is deleted. This resolves certain cases where Verify reports an error of “Node # is not attached to any element and should be deleted.”
· A bug was fixed which could cause problems using the Structured Quads mesh pattern.
· You can now fix certain points in a fully-specified slip surface, so that they will not be moved during slip surface optimization. Use KeyIn Slip Surface Fully Specified to access this feature.
· A “transient” slope stability analysis has been added, allowing you to conduct a stability analysis using every time step in the PWP or Stress file. You can then plot the Factor of Safety vs. Time using Draw Slip Surfaces in CONTOUR.
· Entry & Exit slip surfaces can now specify a radius in order to better control the position of the slip surface center point.
· SOLVE has been further optimized for speed. It is now at least twice as fast compared to 7.03 for most problems.
