Last updated December 19,
2008.
· A bug was fixed which prevented some sketch text fields which worked in version 7.12 to work in 7.13.
· A bug was fixed which caused some sketch text marked as visible in “this analysis only” to revert back to “all analyses” when the analysis was solved. (KB726)
· When exporting to DXF, a new option “Export All Layers” allows you to choose whether to export only those items that are visible (based on the current view preferences) or all items.
· A bug was fixed which could cause GeoStudio to crash when exporting to DXF.
· The behavior of editable drop-down listboxes has been changed to be similar to normal edit boxes. For example, hitting return will not close the dialog. This also fixes a problem which could cause GeoStudio to crash while editing values in drop-down listboxes.
· A bug was fixed which caused GeoStudio to crash in KeyIn Analyses if an analysis’ initial conditions were linked to a deleted analysis in an external file.
· A bug was fixed which could cause GeoStudio to crash when opening a v6 file containing a very large number of regions.
· A bug was fixed which could in certain cases generate an invalid mesh when a floating (circular) region is drawn over another region.
· A bug was fixed in calculating function derivatives, giving incorrect values in extreme cases, such as when graphing the slope of a function at very large x values.
· A bug was fixed in Draw Graph which could make it difficult to select an interface line.
· A bug was fixed in Draw Graph which could result in invalid graphs.
· A vague error message reported by some solvers (“Function cannot return a value”) has been reworded to be more helpful.
· A bug was fixed in the computation of drained strength during a staged rapid drawdown.
· A bug was fixed in the calculation of the tension crack water force when there is ponding water on top of the tension crack.
· Changes were made to the S=f(Datum), S=f(Depth) and other related models to restore functionality available in v6 that had been removed in v7:
o The Rate of Change can now be either positive or negative.
o The label “C-Maximum” will change to “C-Minimum” if the rate of change is negative.
· The Rate of Change field now displays units.
· The name of a field in Sketch Text was mis-typed and has been corrected.
· A bug was fixed related to how a boundary condition applied to an element edge was reconciled with one at a node on that edge. Previously SOLVE would fail to get a solution if a flux boundary condition (q) on a line shared a node with a primary variable condition (H).
· A bug was fixed which could cause SOLVE to crash when a q vs time function boundary condition was applied to a face without also using a modifier function.
· A bug was fixed related to how a boundary condition applied to an element edge was reconciled with one at a node on that edge. Previously SOLVE would fail to get a solution if a flux boundary condition (q) on a line shared a node with a primary variable condition (H).
· A bug was fixed which could cause SOLVE to crash.
· A bug was fixed related to how a boundary condition applied to an element edge was reconciled with one at a node on that edge. Previously SOLVE would fail to get a solution if a flux boundary condition (q) on a line shared a node with a primary variable condition.
· A bug was fixed related to how a boundary condition applied to an element edge was reconciled with one at a node on that edge. Previously SOLVE would fail to get a solution if a flux boundary condition (q) on a line shared a node with a primary variable condition (T).
· A bug was fixed which could cause SOLVE to crash when a q vs time function boundary condition was applied to a face without also using a modifier function.
· A bug was fixed related to how a boundary condition applied to an element edge was reconciled with one at a node on that edge. Previously SOLVE would fail to get a solution if a flux boundary condition (q) on a line shared a node with a primary variable condition (e.g., H).
· A bug was fixed which could cause SOLVE to crash when a q vs time function boundary condition was applied to a face without also using a modifier function.
· Holding down the Alt key while drawing temporarily disables grid snapping.
· The snap to grid option defaults to on for new files.
· Spatial functions can be linearly interpolated rather than kriged. In some cases this is a more intuitive interpolation method.
· Improvements to contouring spatial functions make the contours more accurate.
· Initial conditions are now applied in the following order of precedence: previously computed nodal values; material activation values; generated initial condition values (e.g., from a spatial function); and finally default values for the parameter. Previously different products used different orders.
· A bug was fixed in Modify Objects to make it snap to the grid properly when moving point loads.
· Change to Sketch Text: Errors in field names are now displayed, rather than hiding the entire block of text. They also use a shorter name for readability.
· When a file is upgraded from an older version of GeoStudio and some features could not be upgraded automatically, a list of these issues can be displayed in another window, and is also saved to disk to be referenced later if necessary.
· A bug was fixed which caused GeoStudio to crash in Modify Objects when the center point of a circular region was dragged onto the radius point.
· A bug was fixed which could cause GeoStudio to crash if some sketch text references data from another analysis.
· A bug was fixed which caused GeoStudio to crash under Windows 2000 in KeyIn Functions when clicking “Edit Data Points” or “View Slope of Function”.
· In an error message about the System Clock being reset, the message has been reworded to give more information on how to correct the problem.
· A bug was fixed which could cause GeoStudio to crash in some situations when closing Draw Graph.
· When no licenses are found (or when using a viewer or student license), an info bar is displayed at the bottom of the start page with a link to geo-slope.com to download or purchase license files.
· When searching example files from the start page, searching for a product name (like “SLOPE/W” or “kind:slope”) returns only examples of that kind.
· When opening an example from the search page, the example opens in a new instance of GeoStudio, so the current file does not need to be closed.
· The start page now allows searching for examples on the geo-slope.com web site.
· When a DXF is imported as an image, the DXF’s coordinates can be used for positioning and sizing the image.
· Some bugs were fixed which prevented certain DXF files from being imported (such as those with proxy objects).
· A bug was fixed which introduced small errors in region coordinates when exporting to DXF, sometimes preventing the DXF from being re-imported.
· A bug was fixed which caused the minimum extents to be ignored when importing DXFs as regions.
· A bug was fixed which could cause GeoStudio to crash when exporting to DXF.
· KeyIn Spatial Functions now allows the function to be previewed on the screen even if it has not been applied to any regions.
· Verify now checks for overlapping geometry lines.
· The Materials tab in Sketch Text fields now shows the same list of material properties as the report or View Object Information.
· A bug was fixed which could sometimes cause a toolbar to start being dragged simply by clicking a toolbar button while a dialog box was open.
· A bug was fixed which could produce unexpected data in a dialog box if the file was saved while the dialog box was displayed (such as KeyIn Points). Now dialogs are closed when saving.
· Verify catches file names that are too long. Previously it could miss some cases.
· A bug was fixed which could cause GeoStudio to crash when creating a new analysis when no other analysis exists yet.
· A bug was fixed which could display contours over null elements.
· A bug was fixed in KeyIn Functions which did not display cycling step functions as steps after the first cycle. (The function itself was correct, only the display was wrong.)
· A bug was fixed which could cause the graph axis to have incorrect or missing labels.
· A bug was fixed which caused some drop-down lists to be displayed very small on Windows 2000.
· A bug was fixed which could cause GeoStudio to crash when cloning an analysis that included sketch text fields.
· When a template is marked as [default], it will be selected automatically in the File New dialog box.
· A bug was fixed which caused GeoStudio to crash when run on a computer with a Pentium II or lower processor. Instead, GeoStudio will now display an error message and then exit, as only Pentium III and better processors are supported.
· A bug was fixed in importing version 5 files. For the finite-element products (all products except SLOPE/W), if the view preferences were set to display materials but not the mesh, then materials were not displayed after the import.
· A bug was fixed in importing older files, to ensure all CONTOUR options import properly.
· A bug was fixed in importing older files with a finite element mesh. The mesh was not always imported properly, resulting in unexpected ponding or initial conditions being displayed in DEFINE.
· A bug was fixed to update contours after doing an Undo or Redo.
· A bug was fixed exporting some entities such as contours to DXF.
· A bug was fixed in Draw Graph which would graph the wrong data if you checked the “Current Analysis Only” checkbox in the toolbar while in the process of graphing data from a parent analysis.
· A bug was fixed which could cause DEFINE to display incorrect contours of initial activation values when the values come from another analysis.
· A bug was fixed related to displaying contours in DEFINE when floating/tunnel regions are used.
· A bug was fixed which could cause GeoStudio to crash in certain cases when Add-Ins are selected in KeyIn Functions.
· Added additional control over the convex angles for fully-specified slip surfaces.
· Added additional control over the maximum driving side convex angle, and the maximum resisting side convex angle for optimized slip surfaces.
· To allow for regions with a material intended to represent concrete, when PWP values are read from a finite-element analysis and some PWP values are missing, the hydrostatic force computation no longer returns an error status.
· View Slice Information now has Next and Previous buttons. These buttons or the arrow keys can be used to move to another slice rather than having to click on the slice. This is especially useful when dealing with very narrow slices.
·
For the
GLE method, the FOS closest to zero will be picked in cases where there are multiple
intersecting points. In the past,
the first intersecting FOS was used, but this can be extremely small when a
slip surface has multiple intersecting points.
· A bug was fixed in the hydrostatic force calculation on vertical walls due to piezometric lines when there are multiple vertical walls under the same piezometric line.
· When a point load is selected in KeyIn Point Loads, the point load is displayed in the drawing as selected.
· A bug was fixed which could cause GeoStudio to crash in View Slice Information.
· A bug was fixed in Draw Point Loads to properly snap to geometry objects when clicking near them (for consistency with other draw modes).
· A bug was fixed which caused slip surfaces to not always be truncated correctly along the bottom of the domain.
· A bug was fixed in the Advanced tab of Sketch Text: previously some analysis-specific objects (such as “Slope Objects”) appeared twice in the tree view.
· A bug was fixed which, in some rare cases, would cause certain slip surface slices to not include the bottom-most soil layer.
· A bug was fixed which ignored slices with very small weight.
· A bug was fixed in View Slice Information: the force polygon would not display arrows for forces that were extremely small.
· A new slip surface error condition (983) has been added. This condition is triggered during the critical slip surface searching stage, when missing stress is identified at the slice base center due to interface elements. During the optimization stage, when this happens, optimization stops.
· A bug was fixed which could cause GeoStudio to crash while opening a v6 file, when the file uses pore pressures from a different v6 analysis.
· The optimization process has been enhanced to ensure that the optimized FOS will not be larger than the critical slip surface. Previously this situation could happen in odd cases when the FOS is very sensitive to the number of points in the optimized slip surface (i.e., the critical slip surface is already quite unstable).
·
A bug
was fixed which could cause GeoStudio to crash when viewing custom created
distribution functions in a probability analysis.
·
A bug was fixed to ensure the FOS displayed in
the SOLVE window matches the one displayed in CONTOUR.
· A bug was fixed when importing a v6 file. The piezometric line y coordinate was not imported correctly when the “Adjust Height by” value was blank.
· A bug was fixed in the display of ponded water, occasionally causing vertical white streaks.
· An error message is displayed by SOLVE when no solution can be obtained.
· A bug was fixed to force the piezometric PWP contours to be refreshed after changing the ground surface line.
· A bug was fixed in the graphing of interslice force vs interslice #.
· Only the minimum FOS is displayed in SOLVE even for probabilistic and sensitivity analyses, rather than showing the mean FOS.
· A bug was fixed which could display incorrect values around boundaries between two regions when contouring cohesion depth functions (“S=f(depth)” material model).
· A bug was fixed which could give an incorrect FOS when two region points are defined nearly but not quite vertically and when there is surface ponded water.
· A bug was fixed which caused slide mass data to be missing in the Janbu generalized method.
· A bug was fixed which displayed the wrong FOS in the toolbar for the Janbu generalized method.
· A bug was fixed which could cause GeoStudio to crash when closing a file, when that file was displaying contours of piezometric lines generated from a SEEP/W analysis.
· When the type of a reinforcement is changed, the FOS Dependent Variable gets set to its default for the new type. This is how v6 behaved, but the behavior was changed in v7.
· A bug was fixed which caused GeoStudio to not display water ponding over bedrock.
· A bug was fixed to display the density and distribution functions correctly in Draw Probability.
· A bug was fixed which could cause GeoStudio to take a very long time repainting the screen at a high zoom.
· A bug was fixed which could cause points to disappear unexpectedly, such as when one point is dragged onto another.
· A bug was fixed which could cause SOLVE to crash under certain circumstances where a spatial function is created but not used.
· A bug was fixed in computing the PWP at the base center of a slice when a B-bar and ponded water are used together. The surcharge load will be used in the PWP computation with B-bar, but the ponded water weight will not.
· A bug was fixed in the computation of hydrostatic forces on vertical boundaries. Previously hydrostatic forces were always computed when a piezometric line appeared on the vertical boundary, even if the material on that boundary did not specify a piezometric line.
· A bug was fixed in the soil pile shear load computation. Previously the shear load was always added even if the pile did not intersect the slip surface.
· A change was made to how SOLVE handles transient analyses with no initial PWP conditions specified. Previously SOLVE would assume a value of Head = 0, but that could result in very high negative pressure values, and it is not consistent with the behavior for a steady-state analysis. Now the default value is Head = Elevation.
· A bug was fixed importing Hydraulic boundary conditions from a v6 file.
· SOLVE avoids falsely converging on the first iteration of a steady-state analysis.
· Verify checks that initial conditions for PWP are defined for a transient analysis. An initial condition of “None” is allowed as long as every material used in the analysis has an Activation value defined.
· The H vs Vol BC function now allows for potential seepage face above the elevation defined by the function.
· A bug was fixed which could cause GeoStudio to crash when graphing a Fredlund/Xing function.
· SEEP/W uses new default values for certain convergence parameters, to more easily solve a variety of problems without having to change convergence options.
· A bug was fixed which prevented a material’s initial PWP from being used when it was set to 0.
· A bug was fixed which could sometimes cause small contour variations to be drawn when contouring Total Head.
· Changes have been made to the Newton-Raphson elastic-plastic solution scheme. These changes make it possible to obtain converged solutions for a much wider range of problems. The new scheme will result in computed deformations somewhat different from what was obtained with the old scheme, particularly when the loading approaches the point of limiting equilibrium. Computed deformations under working-load conditions, however, should not be significantly different from those obtained with the old solution scheme.
· Add-Ins have been changed such that for total stress materials in a consolidation analysis, the material model is not set to be “effective with no pwp”, as it is for a load deformation analysis.
· The K “reduction” factor can now be greater than one, thereby amplifying K rather than reducing it.
· If one region used an “effective with pwp” material while its neighbor used “effective with no pwp”, in some cases drawing contours of excess pwp in the “effective with pwp” region would not display contours in some random elements. This has been fixed.
· The H vs Vol BC function now allows for potential seepage face above the elevation defined by the function.
· A bug was fixed which could cause GeoStudio to crash in Draw Mohr Circle.
· A bug was fixed which would give incorrect strains for fill materials in an EP model.
· A bug was fixed to allow a value of .49 for Poisson’s ratio, and a value of 100 for Degree of Saturation.
· “Spring Constant vs Displacement” functions are once again supported (they were in v6, but had been removed in v7).
· A bug was fixed which could cause GeoStudio to crash when graphing a Fredlund/Xing function.
· SIGMA/W uses new default values for certain convergence parameters, to more easily solve a variety of problems without having to change convergence options.
· A bug was fixed which prevented a material’s initial PWP from being used when it was set to 0.
· A bug was fixed which would incorrectly compute a displacement vs time boundary condition on the second step.
· A bug was fixed in View Object Information which could show the wrong initial conditions applied to a region if an initial activation value was specified and then the material model changed to one that does not include initial activation data.
· A bug was fixed in some graphs. Spectral Acceleration, Velocity and Distance plots (in Draw Graph) were out by the gravitational constant. The shape was correct, but all values needed to be multiplied by g.
· “Spring Constant vs Displacement” functions are once again supported (they were in v6, but had been removed in v7).
· Verify checks that a G Reduction function is defined for the Quake Equivalent Linear model.
· QUAKE/W uses new default values for certain convergence parameters, to more easily solve a variety of problems without having to change convergence options.
· A bug was fixed which could cause GeoStudio to crash in Draw Mohr Circle.
· A bug was fixed which caused latent heat to be underestimated by 1/water content when using the simplified thermal model.
· TEMP/W uses new default values for certain convergence parameters, to more easily solve a variety of problems without having to change convergence options.
· Verify checks that initial conditions for temperature are defined for a transient analysis. An initial condition of “None” is allowed as long as every material used in the analysis has an Activation value defined.
· A bug was fixed which prevented a material’s initial PWP from being used when it was set to 0.
· A bug was fixed which could potentially use an initial temperature of 0 instead of the user-specified phase change temperature.
· A bug was fixed importing Contaminant boundary conditions from a v6 file.
· A bug was fixed which prevented CTRAN/W from being used with a VADOSE/W transient analysis.
· CTRAN/W uses new default values for certain convergence parameters, to more easily solve a variety of problems without having to change convergence options.
· A bug was fixed which prevented a material’s initial PWP from being used when it was set to 0.
· A bug was fixed which prevented AIR/W from using spatial functions for initial air pressure in some cases.
· VADOSE/W now supports thermosyphons.
· A change was made to how SOLVE handles transient analyses with no initial PWP conditions specified. Previously SOLVE would assume a value of Head = 0, but that could result in very high negative pressure values, and it is not consistent with the behavior for a steady-state analysis. Now the default value is Head = Elevation.
· Verify checks that initial conditions for PWP and Temperature are defined for a transient analysis. An initial condition of “None” is allowed as long as every material used in the analysis has an Activation value defined.
· Added the option to specify initial temperatures in KeyIn Analyses for VADOSE/W Transient Isothermal analyses.
· The H vs Vol BC function now allows for potential seepage face above the elevation defined by the function.
· A bug was fixed importing Hydraulic and Gas boundary conditions from a v6 file.
· A bug was fixed which prevented CTRAN/W from being used with a VADOSE/W transient analysis.
· A bug was fixed which could cause GeoStudio to crash when graphing a Fredlund/Xing function.
· A bug was fixed which prevented a material’s initial PWP from being used when it was set to 0.
· A bug was fixed which could potentially use an initial temperature of 0 instead of the user-specified phase change temperature.
· A bug was fixed which could sometimes cause small contour variations to be drawn when contouring Total Head.
· A bug was fixed which caused the solvers to crash when run on Korean Windows. (KB723)
· A bug was fixed in Set Page which prevented the units from being saved. (KB722)
· 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, yo
