the intersecting point between the slip surface and an anchor load when the
anchor is applied in the perfectly vertical direction.
· A bug has been fixed which could cause the factor of safety to be computed too low when using a non-linear soil model and with the “Ignore seismic load in base shear strength calculations” option checked.
· Previously if the Factor of Safety file could not be opened, a blank window would be displayed. Now an error message will explain why the file cannot be opened.
· A bug has been fixed in SLOPE/W SOLVE which in very specific cases would display a different factor of safety in the solver window than the actual factor of safety in the .FAC file. (SLOPE/W CONTOUR would always correctly display the value from the .FAC file.)
· A bug was fixed which could cause the application to stop responding when exporting a DXF. (KB486)
· A bug has been fixed which could cause the K-sat value to change when switching between log and arithmetic views. (KB487)

·
The change in heat stored in the bottom layer
of snow has been added to the snow base energy balance equation to determine
the snow base temperature. (KB478)
·
When using modifiers on climate data,
TEMP/W SOLVE was not using the scaled data, it always
used the original values. This has been
fixed. (KB479)
·
A bug has been fixed which caused TEMP/W
SOLVE to read longitude for latitude and vice versa, when using climate data. (KB476)
·

· A bug has been fixed which would cause CONTOUR to shut down without warning if it was not launched from DEFINE.
·
In some configurations, when clicking on
an application’s shortcut in the Start menu, Windows Installer would display a
message about re-creating the shortcut or fixing the application. In a few cases it would even prompt for the
CD. This has been fixed. (KB461)
· A bug was fixed which prevented CONTOUR from opening some files. (KB469)
·
When a solution could not converge during
· A bug has been fixed which prevented the Draw PWP dialog box from being closed. (KB464)

· When changing the Method using View – Method in the menu, the minimum slip surface was not being selected. This has been fixed.
·
SOLVE now checks for unreasonably steep
exit angles of trial slip surfaces. An
Invalid Slip Surface (FOS = 995) is presented when the exit angle of a trial
slip surface is larger than 45 degrees. (KB468)
· A bug has been fixed which displayed the wrong factors of safety in the Draw Slip Surfaces listbox for CE1, CE2 and LK. (KB472)
· Now supports up to 999,999 time steps.
· A bug was fixed which caused an error message to be displayed when importing a TEMP/W file. (KB462)
· A bug was fixed which would cause CONTOUR to display some initial condition values as 0. SOLVE has always been using the correct initial conditions; the bug only caused CONTOUR to display incorrect values. (KB466)
· When drawing multiple elements with the Preview mode turned on, the mesh will now correctly refresh itself when the material number is changed.
· In some cases the SOLVE graph cannot be displayed (due to invalid data). Rather than displaying an error message in those cases (which would halt the solver) the graph is now simply not updated.
· When defining a volumetric water content function, an Mv of 0 is not valid. Previously this invalid data was only caught in the solver. Now it is caught in DEFINE.
· When the water content was saved in view log suction mode, the predicted conductivity functions for the Green & Corey or Fredlund & Xing methods could give incorrect Ksat values, depending on the steepness of the function. This has been corrected. (KB463)
· Now supports up to 999,999 time steps.
· The Tools Verify command in SIGMA/W DEFINE now checks that initial conditions are not over-specified. For a Load/Deformation or Consolidation analysis, you must specify either an initial water table or use an external PWP or Head file.
· A water table that curves back on itself is not valid in SIGMA/W, though it is valid in other applications. Previously you could import such a water table from SEEP/W into SIGMA/W, but SIGMA/W would distort it to avoid the invalid state. SIGMA/W has been improved to avoid this situation or to warn the user of invalid water tables. The handling of imported water tables in general has also been improved. (KB457)
· A bug has been fixed which would prevent CONTOUR from reading the results of an Insitu analysis if the analysis’ first time step was marked as “don’t save”.
· When drawing multiple elements with the Preview mode turned on, the mesh will now correctly refresh itself when the material number is changed.
· A bug has been fixed which caused some old initial condition files (*.*in) to not be deleted at the beginning of a solve.
· When initial conditions were selected from a SIGMA/W stress file, the solver would instead look for a QUAKE/W stress file (and typically not find it). Now it correctly identifies the SIGMA/W file.
· Now supports up to 999,999 time steps.
· When drawing multiple elements with the Preview mode turned on, the mesh will now correctly refresh itself when the material number is changed.
· A bug was fixed which would cause CONTOUR to display some initial condition values as 0. SOLVE has always been using the correct initial conditions; the bug only caused CONTOUR to display incorrect values. (KB466)

· A bug has been fixed in the duration modification number for quake records. Previously the original duration was always being used.
· When initial conditions were selected from a SIGMA/W stress file, the solver would instead look for a QUAKE/W stress file (and typically not find it). Now it correctly identifies the SIGMA/W file. (KB473)
· Now supports up to 999,999 time steps.
· A bug was fixed which would cause CONTOUR to display some initial condition values as 0. SOLVE has always been using the correct initial conditions; the bug only caused CONTOUR to display incorrect values. (KB466)

Fixed a bug related to reading in the
volumetric water content function. The
bug would cause this error message to display while solving: “Unable to fit spline curve to soil-water
characteristic curve.” (KB410)

· A bug was fixed which caused all time values to be zero when plotting against time in the Draw Graph mode. (KB411)
· Two free licenses are now included with each GEO-SLOPE Office application: a Student License and a Viewer License.
The Student License is designed as an aid to learning geotechnical analysis. It is an ideal teaching tool for university professors both at the undergraduate and graduate levels, and includes documentation and example problems that can be used as a guide for developing class curriculum. The Student License is a limited version of the software; however, sufficient features are available for learning the basics of geotechnical analysis.
The Viewer License (previously called an Evaluation License) can be used to review geotechnical problems that have been analyzed with the full-featured software. The Viewer License enables all of the features in CONTOUR, allowing you to contour, plot and view results from a previously analyzed problem.
Both the Viewer License and Student License are free of charge and are included when you install Version 5.1. When you run the software without a full-featured license, you can select either free license. You may freely distribute both the Viewer and Student Licenses, provided you adhere to the included license agreement.
· Each GEO-SLOPE Office application is now certified as Windows XP Compatible. GEO-SLOPE Office will run on Windows 95, 98, ME, NT, 2000, or XP.
· An axis (Sketch Axis) drawn in DEFINE can now be shared with CONTOUR just as other sketch objects (lines, text, etc.). (KB384)
· Common dynamic sketch text (Project ID and Soil Properties in SLOPE/W) is now shared between DEFINE and CONTOUR. SLOPE/W CONTOUR dynamic text slide mass and probability still cannot be shared because the corresponding information does not exist in SLOPE/W DEFINE. Also, when you convert a Version 4 data file to Version 5 in DEFINE, all sketch objects will now be shared.
· An arbitrary color is assigned to the DXF drawing layer when exporting to a DXF file so that AutoCAD does not lock the layer. (KB370)
· A splash screen has been added to all products when they are launched. If a license will be expiring shortly, the splash screen will contain a link to the GEO-SLOPE web site to renew the license.
· The Help About box now contains a button which links to the GEO-SLOPE web site to help in purchasing or renewing a license. Additional license information is also displayed in the Help About box.
· The Set Scale command sometimes displayed a slightly incorrect scale when feet were selected for engineering units. For example, the y-scale would change to 200.01, even though 200 had been entered. This has been fixed. Also, the Lock Scales option in the Set Scale command did not always lock scales the first time scales were changed; this has also been fixed. (KB392)
· A bug was fixed which could cause contours to be drawn outside the mesh bounds. (KB390)
· A number of bugs were fixed relating to the operation of Undo/Redo in specific modes or commands. (KB391, KB383)
· A bug was fixed which would cause the Set Page dialog to contain invalid values when no default printer was installed. (KB394)
· A bug was fixed which could cause the application to crash if the default printer was offline. (KB395)
· When moving problem data files to another folder, imported pictures would sometimes have to be located manually the next time the file was opened. This has been improved.
· A bug was fixed which would cause dialogs to appear in odd locations when the application was running in a secondary monitor on a computer equipped with multiple monitors.
· SLOPE/W can now consider the pore-water pressures generated from a VADOSE/W analysis.
· The KeyIn Points command in SLOPE/W DEFINE can now copy and paste point coordinates directly into the dialog box. A context menu is displayed when you right-click on list box. This allows you to import and export point coordinates between SLOPE/W and other programs, such as AutoCAD and Microsoft Excel.
· The KeyIn Lines command in SLOPE/W DEFINE can now copy and paste point numbers. This allows you to quickly replicate points from one soil line to another.
· The GLE method has been improved so that convergence will be achieved in almost all cases, regardless of the problem’s sliding direction. This has been done by increasing the number of lambda values to 11 from 6, and changing the default lambda range to be from -1.25 to +1.25.
· The Verify command caused the slip surface grid points to appear as a straight line if the grid was defined counterclockwise. This has been fixed. (KB403)
· In some rare cases when using the rigorous method and a small tolerance, SLOPE/W CONTOUR would display some factors of safety as 0.00. This has been fixed. (KB404)
· In some rare cases when the mass was small (i.e., a very shallow slope) and the load on the slope was very large, a factor of safety less than 1.0 would be computed, because the slope was actually failing uphill. This has been resolved so that slopes cannot fail uphill; an unconverged factor of safety is displayed in this case. (KB406, KB407)
· A bug was fixed in the handling of slip surfaces cutting a vertical soil line with vertical tension crack line and/or vertical piezometric line.
· A bug was fixed which caused the wrong factor of safety to be displayed when no solution was obtained in the GLE method.
· A bug was fixed which caused lambda values to always be positive.
· A bug was fixed which caused the wrong values to be displayed in the View Slide Mass dialog when using the Corps of Engineers #1, Corps of Engineers #2 or Lowe-Karafiath methods. (KB408)
· A bug was fixed in the Draw Slip Surfaces command that prevented the minimum block slip surface at a point from being selected when viewing the GLE method.
· When changing the method to display while you are in the Draw Slip Surfaces command, SLOPE/W now keeps displaying the current slip surface number, rather than automatically selecting the minimum slip surface for the new method. To view the minimum slip surface, you can click on the “Min. Factor of Safety” button.
· When running CONTOUR under Windows 95, 98 or Me and choosing View Slip Surfaces with a very large number of slip surfaces, the View Slip Surfaces dialog would take a very long time to close, and the application would appear to be hung. This issue has been fixed. (KB386)
· The Draw Single Elements and Draw Multiple Elements commands have been combined into a new Draw Elements command. This new command speeds up mesh definition, allowing you to continuously create elements and element regions without exiting the mode. The new Draw Elements command contains several enhancements that will speed up mesh definition, such as automatic mesh preview and default increments that match previously generated elements. See Draw Elements in Chapter 4 of the online help for more details.

See Draw Elements in Chapter 4 and the Elastic-Plastic Soil Model in Chapter 7 of the online help for more details.
· A consolidation analysis using the direct solver in Version 5.0x used an excessive amount of memory, which greatly increased the solution time for large problems. The memory requirement has been reduced significantly in Version 5.1.
· When saving a previously-solved transient analysis as a different file name (without the solution), the starting time step was not initialized properly. This has been fixed.
· Errors in the unbalanced load norm convergence criterion have been fixed. (KB385)

· A bug was fixed which sometime caused SOLVE to never find a solution when using review boundary conditions in a consolidation analysis.
· When selecting the View List option in KeyIn Material Properties, the dilation angle value was labeled as "E modulus" if you were using an elastic-plastic model. This has been fixed.
· You are now prompted to generate an initial water table whenever you select a PWP file or head file. This allows you to generate initial pore-water pressure conditions from the imported file. You can then modify or remove the generated initial water table using the KeyIn Initial Water Table command. Previously, SIGMA/W Version 5 generated the initial water table each time you hit the OK button in Analysis Settings.
· Changed default iterative solver convergence parameters to give a smaller convergence tolerance.
· Memory requirements for a SOLVE analysis have been reduced, especially for problems with large meshes.

· Changed default iterative solver convergence parameters to give a smaller convergence tolerance.
· Memory requirements for a SOLVE analysis have been reduced, especially for problems with large meshes.
· Added feature to automatically install GEO-SLOPE license files with specific file extensions. For example, when you double-click on a .gsi_lic or .gsi_network_lic file in Windows Explorer, the License Utility runs and copies the license file into the appropriate Licenses folder.
· All license files in the Licenses folder are now displayed in the License Utility window.

· Lambda values in the GLE method are now allowed to be either positive or negative.
· A bug was fixed related to water force calculations on vertical walls due to the surface water layer.
· The independent variable combo box in the Draw Graph dialog would sometimes list options that did not make sense. This bug has been fixed. (KB380)
· A bug was fixed which would occasionally cause SLOPE/W DEFINE to crash during a file save in Win95, Win98 or WinME. (KB381)
· When using a different x and y engineering scale, the required reinforcement bond length was not shown perpendicular to the reinforcement in the CONTOUR window. This problem has been fixed. (KB382)
· Fixed a bug in Undo/Redo that would corrupt climate data. (KB377)
· When dynamic sketch text that made sense in CONTOUR was shared with DEFINE, or vice versa, DEFINE would display nonsense or would crash. This bug has been fixed by not allowing dynamic sketch text to be shared between DEFINE and CONTOUR. (KB371)
· After importing a DXF file (Import Picture) and saving the model to a GEO-SLOPE file, the DXF image failed to be read in when the GEO-SLOPE office file was opened again. This bug has been fixed. (KB368)
· In some cases, slip surfaces through vertical slopes were not being generated correctly. This has been fixed. (KB372)
· A bug has been fixed which caused SLOPE/W DEFINE to crash when an object was selected with the Modify Objects dialog and (1) the Slip Surface option (specified in Analysis Settings->Control) required a slip surface grid and (2) no grid had been defined.
· When soil numbering was changed (via "Delete" or "Insert" buttons in the KeyIn - Soil Properties dialog), dynamic sketch text linked to a soil was not updated correctly. This bug has been fixed.
· In the View Slide Mass dialog, the Total Resisting Moment and Total Activating Moment of the Ordinary method are now being displayed. (KB373)
· The slip surface projection angles for left and right blocks have been adjusted to be consistent with active and passive earth pressure theory to prevent projection angles from being too large.
· When reading a FE mesh in SLOPE/W CONTOUR, the engineering units and material colors are now being read in correctly. (KB369)
· In SLOPE/W DEFINE, Verify now correctly reports if no PWP file has been selected. Previously it would report a missing PWP file even when one had been selected. (KB374)
· SEEP/W is now able to use either an iterative or a direct solver.
· When an Mv constant is used in a log scale water content function, the function was not properly interpreted in SEEP/W SOLVE. This has been fixed.
· A bug was fixed which occasionally caused an incorrect y-conductivity value to be displayed. (KB375)
· SIGMA/W is now able to use either an iterative or a direct solver.
· Fixed a bug reading .SEZ files when the water content function was Log and an Mv constant was being used.
· TEMP/W is now able to use either an iterative or a direct solver.
· In QUAKE/W CONTOUR you can now contour CSR (Cyclic Stress Ratio). CSR has been added to the Contour Parameter list under the Draw Contour command.
· CTRAN/W is now able to use either an iterative or a direct solver.
· Minor bug fixes.
· Fixed a bug which would cause Seep1.exe to crash when reading in v5 data files which used modifier functions. (KB366)
· The FLEXlm security system has been improved, making it easier to manage licenses.
· Undo/Redo support has been improved. (KB362, KB364)
· The iterative solver in CTRAN/W, SEEP/W, SIGMA/W and TEMP/W has been improved.
· A problem was fixed where, when opening a data file with an initial condition file specified but the specified time step was no loner valid, DEFINE would refuse to open the data file. Now a warning is displayed and the time step is reset to a default value.
· A problem was fixed which prevented keyboard shortcuts to be used in the solver while a solve was in process.
· A bug was fixed in all tabbed dialog boxes (in particular the KeyIn Analysis Settings dialog). Previously if a change in one tab affected settings on another tab, the second tab would not be updated until the OK button was hit. (KB361)
· Corrections have been made to the documentation and online help.
· New modified submerged unit weight method for initial static analysis by using water head from SEEP/W results or PWP from SIGMA/W results and a user defined water table.
· The water table can be generated automatically by defining an initial PWP file from SEEP/W or SIGMA/W results for initial static analysis.
· SEEP/W now supports single-point functions.
· Several bugs have been fixed related to editing functions, especially when using the "Use Log Suction" option.
· A new modified submerged unit weight analysis type has been added, called Insitu2, for initial stress analysis using water head from SEEP/W or PWP from SIGMA/W and a user-defined water table. More details on the Insitu2 analysis can be found in the online help.
· The water table can be generated automatically by defining an initial PWP file from SEEP/W or SIGMA/W results for the initial stress analysis.
