Change: When importing regions from a DXF or DWG file, an error message will be displayed if the source file contains regions on multiple planes.
Change: A new "Viewing Results" section has been added to the Online Help.
Bug fix: In KeyIn Analyses, when trying to change only the case of letters in an analysis name, an error would be displayed about duplicate analysis names.
Bug fix: When a file with no regions was exported as a GeoStudio 2007 file, GeoStudio 2007 would display an error about some unexpected tags.
Bug fix: If Draw Materials is started in a finite element analysis and the "Lines" option is selected, then a Slope analysis is activated, the Draw Materials dialog should switch back to the "Regions" option.
Bug fix: GeoStudio could crash in Results view if no results are available.
Bug fix: In View Result Information, selecting nodes by dragging a rectangle could sometimes be extremely slow.
Bug fix: In some cases, opening a file created by GeoStudio 2004 (version 6) would end up creating several boundary conditions and contours with identical names.
Bug fix: Hitting "Esc" in the "Set Locations" mode of KeyIn Spatial Functions would exit the KeyIn Spatial Functions mode entirely rather than just exiting the Set Locations mode and reverting to the main dialog.
Bug fix: Text on toolbar buttons was not always displayed in the correct language.
Bug fix: GeoStudio may crash when defining a Convective Surface Fluid temperature function. (This was a regression introduced in 8.13.0.)
Bug fix: Imported WMF pictures were not displayed properly. (This was a regression introduced in 8.14.0.)
Bug fix: In some cases the Solve Manager window could incorrectly report that an analysis had "Results out of date" even immediately after solving it.
Bug fix: Downgrade reports created by GeoCmd were empty.
Bug fix: With the "Mesh" View Preference turned on, drawing a material on a region which previously did not have a material, the mesh would not be displayed in that region. The problem could be worked around using View - Redraw, manually regenerating the mesh using Draw - Mesh Properties, saving the file, or solving. (This was a regression introduced in 8.14.0.)
Bug fix: An AddIn's time parameters (such as eElaspedTime) could be incorrect if many analyses with different analysis kinds (SEEP/W, SLOPE/W, etc) are solved simultaneously.
Bug fix: Child analysis of a Convective or Density Dependent analysis fails to solve with error, "Cannot read the results file required to solve this analysis. File not found: ..."
Bug fix: Changes to view preference does not affect "View Object Info" mouse mode.
Bug fix: The Esc key did not exit the current drawing mode. (This was a regression introduced in 8.14.0.)

Bug fix: GeoStudio may crash when opening a file containing non-latin characters on a computer with a different locale setting. (This was a regression introduced in 8.14.0.)
Bug fix: In some cases a .GszXmlBackup file was not generated. This is a temporary backup file generated while the .gsz is being modified, in case the .gsz gets corrupted.
Bug fix: In some cases GeoStudio did not allow modification of surface regions using Modify Objects or Draw Surface Layers. The error "Unable to generate surface region and regions above it" was displayed. This was a regression introduced in version 8.14. In some cases GeoStudio would crash while attempting to mesh surface regions.

SLOPE/W

Feature: SLOPE/W now includes full support for Partial Factor analysis, including limit state design approaches such as Eurocode 7 and British Standard 8006. Read the engineering manual "Stability Modeling with SLOPE/W" for details.
Feature: SLOPE/W now includes new slip surface inspection and visualization options. Use the new Draw Slip Surface Color Map command to display slip surfaces, contours, and the safety map using the same color ranges.
Feature: Display all potential slip surfaces at once, color-coded according to their factor of safety.
Feature: The Slip Surfaces docking window now allows you to filter the list of slip surfaces to a specific range.
Feature: Select a slip surface in Results view by clicking points of the slip surface definition (such as a center point, or an entry or exit point). The most critical slip surface associated with that definition will be selected.
Feature: Get fisual feedback about slip surfaces while graphically selecting them, including a tooltip showing factor of safety and a graphical representation showing the slip surface center and radius lines.
Feature: More control over view preferences in Results view: choose whether to display the current slip surface (includes the slip surface line itself, shading, slices, and factor of safety label); choose whether to display the critical slip surface above all others; and choose whether to display the slip surface definition objects.
Feature: Reinforcement in the passive zone is now applied if the resulting reinforcement load is acting in a direction causing the slope to give a higher factor of safety.
Feature: Reinforcement properties can now be included in probabilistic and sensitivity analyses.
Feature: Newmark analyses now display KMax - the maximum average acceleration from the side of the acceleration record with the largest area above (or below) the yield acceleration. Such analyses may return improved velocity and displacement values in some rare cases.
Feature: The Slip Surfaces docking window allows you to choose what to do with the "current" slip surface when you change analyses: either keep the same slip surface number selected, or switch to the critical slip surface of the new analysis.
Feature: The Slip Surfaces docking window allows you to type a slip surface number to select it.
Feature: The Slip Surfaces docking window is now more responsive when displaying a large number of slip surfaces.
Change: Water surcharge now is excluded in the pore-water pressure calculations using B-bar/Ru coefficients
Change: Speed improvements were made to Results View for analyses with a large number of slip surfaces.
Change: Many SLOPE/W example files have been updated.
Bug fix: Under some rare circumstances, the SLOPE/W solver could stop responding (hang).
Bug fix: Graphs displayed using Draw Sensitivity or Draw Probability did not update when the current slip surface changed.
Bug fix: Graphs displayed using Draw Graph did not update when the current slip surface changed.
Bug fix: The default unit weight of water assigned to a tension crack was incorrect when using imperial units.
Bug fix: It was not possible to add new Lambda Values when the list of Lambda Values for the Linear Search method was empty.

Bug fix: In some cases for a Monte-Carlo analysis, when Cohesion and Phi are both specified in Set Probabilistic Parameters and a C-Phi correlation coefficient is specified, results may be incorrect.
Bug fix: In rare scenarios GeoStudio is unable to read results generated by a sensitivity analysis.
Bug fix: Some shallow slip surfaces may not be generated.
Bug fix: When editing some of the SLOPE/W lines using the KeyIn commands, the points on the line were not always displayed in sorted order. This bug specifically affected piezometric lines, fully specified slip surfaces, surcharge lines and tension crack lines.
Bug fix: View Object Information did not display any information about the axis of rotation.
Bug fix: In Draw Graph in a sensitivity analysis, the Run combo box was not displaying properly when multiple modifiers were being used.

SEEP/W

Change: The Plan View analysis in SEEP/W ensured that the saturated conductivity of a K-function was used even if the pore-water pressure was negative. Although the restriction is theoretically correct, it prevented an add-in material model from receiving the actual solved pore-water pressure when it was negative. The restriction was removed because the Saturated Only model can be used in place of the Saturated-Unsaturated material model to ensure the saturated conductivity is used in the Plan View analysis.
Bug fix: GeoStudio could potentially crash after a flux section was selected.

SIGMA/W

Bug fix: In some cases for axisymmetric analyses with a central angle of 360 degrees, the verification error "Neither force nor displacement has been applied in this analysis" would be reported incorrectly.

TEMP/W

Bug fix: Climate data import did not work. (This was a regression introduced in 8.14.0.)
Bug fix: GeoStudio could potentially crash after a flux section was selected.

CTRAN/W

Bug fix: GeoStudio could potentially crash after a flux section was selected.

AIR/W

Bug fix: GeoStudio could potentially crash after a flux section was selected.

VADOSE/W

Bug fix: Climate data import did not work. (This was a regression introduced in 8.14.0.)
Bug fix: GeoStudio could potentially crash after a flux section was selected.

8.15.1.11236

These additional changes were made in version 8.15.1.11236

All Products

Bug fix: Unable to run license maintenance check while upgrading to 8.15.
Bug fix: Upgrading from 8.14 to 8.15 loses all non-English languages.

8.15.2.11331

These additional changes were made in version 8.15.2.11331

All Products

Feature: When typing coordinates in the status bar while in a draw mode, you can now specify a relative point with an angle and an X or Y offset. For example: @x10<30 will move 10 units to the right and up 30 degrees.
Change: Minor performance and stability improvements.
Change: Improved meshing reliability.
Bug fix: Floating regions could not always be selected using Modify Objects. In some cases the domain region below it would be selected instead.
Bug fix: Merge Regions may not merge two adjacent regions properly.
Bug fix: In Draw Mesh Properties, the mesh is not updated after clicking “Remove Constraints”. You can force the mesh to update by applying other constraints or modifying the geometry. This bug was a regression introduced in version 8.14.
Bug fix: In some cases a solver may fail while attempting to reference initial conditions from a steady state analysis, and display an “Invalid time step” error.
Bug fix: In some cases GeoStudio may crash while editing initial conditions in KeyIn Analyses.
Bug fix: GeoStudio could crash when clicking "Copy" in View Result Information. This bug was a regression introduced in version 8.15.0.
Bug fix: In View Result Information, dragging a rectangle could select the wrong gauss points.
Bug fix: View Result Information is now faster when selecting a large number of nodes.
Bug fix: Some parts of the software always appeared in English, even if the rest was displayed in a different language. This bug was a regression introduced in version 8.15.0.
Bug fix: A few issues were fixed related to translations in various languages.
Bug fix: A DWG or DXF imported as a Sketch Image would hide any other images behind it. This bug was a regression introduced in version 8.15.0.
Bug fix: File Export incorrectly listed AutoCAD DWG files as an option for exporting. Currently the only AutoCAD file type supported for exporting is DXF.
Bug fix: In some cases, especially with very small regions, importing regions from DXF may cause GeoStudio to crash.
Bug fix: When using licenses tied to multiple USB dongles with 64-bit Windows, GeoStudio was only able to detect one of the USB dongles. This bug was a regression introduced in version 8.15.0. With this new release, all USB dongles will be detected by default, but in order to run GeoStudio from a remote desktop you must go to Help - License Management - Local Settings, and check the "Use 64-bit Licensing" checkbox. Due to a constraint in the underlying licensing software, 64 bit licensing will only detect a single USB dongle at a time.

SLOPE/W

Bug fix: Not all probabilistic graphs could be viewed. This bug was a regression introduced in version 8.15.0.
Bug fix: Contours were not always updated when changing the time step while in Results View.
Bug fix: When exiting the Draw Entry and Exit mode by right-clicking, the mouse cursor would not be reset.
Bug fix: In View Slice Information, using the keyboard's arrow keys after a mouse click was not changing the selected slice. This bug was a regression introduced in version 8.15.0.
Bug fix: GeoStudio may crash if a SLOPE/W analysis is solved while in the Select Slip Surface mode.
Bug fix: In some cases the Slip Surfaces window may not display properly the first time GeoStudio is run, or after using Window - Reset Window Layout. Closing and re-running GeoStudio will normally solve the problem.
Bug fix: GeoStudio may crash when viewing results of a sensitivity analysis. This bug was a regression introduced in version 8.15.0.

SIGMA/W

Bug fix: In KeyIn Analyses, when getting initial conditions from a parent and that parent is a SIGMA/W Coupled Consolidation analysis, it was not possible to select "(all)" as the time steps.

8.15.3.11339

These additional changes were made in version 8.15.3.11339

All Products

Bug fix: GeoStudio is unable to use Activated licenses on 64-bit Windows. This bug was a regression introduced in version 8.15.2.

8.15.4.11512

These additional changes were made in version 8.15.4.11512

All Products

Improved application stability working with the geometry in GeoStudio. Problems fixed with this change include:

Bug fix: GeoStudio may incorrectly display the error message "Unable to use results from file. The mesh is incompatible with this file" when attempting to load results from another analysis, even though the other analysis was solved using the same mesh.
Bug fix: GeoStudio may crash when modifying region geometry.
Bug fix: GeoStudio may crash when saving a file.
Bug fix: In some cases, especially with very small regions, importing regions from DXF may cause GeoStudio to crash.

These bugs were also fixed:

Bug fix: The Student and Basic Editions may incorrectly indicate there are too many regions, and prevent the file from being saved.
Bug fix: Combo boxes in a toolbar (such as the Contour combo box) may not accurately indicate what is currently selected.
Bug fix: When an analysis was exported to DXF format, legends in the exported drawing appeared as solid white rectangles.
Bug fix: Some changes made in Set Units and Scale that affect the mesh (such as changing the Central Angle for an axisymmetric analysis) would not be applied to the mesh until the next time the mesh was regenerated (such as by making a change to the geometry). This bug was a regression introduced in version 8.15.0.
Bug fix: In File - Import as Regions, in some cases when importing from DWG/DXF an incorrect scale factor was suggested.
Bug fix: Material assignments on a line were not preserved when the line was split.
Bug fix: There was a problem with the DWG/DXF importing where in some cases an incorrect scale factor was suggested. This has now been fixed so the suggested scale more accurately represents the contents of the DWG/DXF file.
Bug fix: Material assignments on a line were not preserved when the line was split.

SLOPE/W

Bug fix: The Slip Surfaces window may display incorrect left and right angles for the optimized slip surface.
Bug fix: GeoStudio could crash when switching to Define view while in Select Slip Surface mode.
Bug fix: Contour labels on the grid of centers (when contouring factor of safety) were not displayed with the user-defined number of significant digits.

SIGMA/W

Bug fix: The starting time and duration may be incorrect for analyses whose type is "SIGMA/W Stress", "QUAKE/W Stress", or "QUAKE/W Newmark Deformation". This bug was a regression introduced in version 8.15.0.
Bug fix: GeoStudio crashes when in Results view for a SIGMA/W analysis that has not been solved. This bug was a regression introduced in version 8.14.

QUAKE/W

Bug fix: The starting time and duration may be incorrect for analyses whose type is "SIGMA/W Stress", "QUAKE/W Stress", or "QUAKE/W Newmark Deformation". This bug was a regression introduced in version 8.15.0.

8.15.5.11777

These additional changes were made in version 8.15.5.11777. We recommend upgrading for everyone whose maintenance covers this release.

All Products

Bug fix: In some cases GeoStudio would not release unused space at the end of a .Gsz file. This caused .Gsz files to be larger than necessary.
Bug fix: After applying a Windows 10 update, activated licenses may no longer function.
Bug fix: The Solve Manager may report 'Results out of date' when in fact nothing has changed.
Bug fix: When printing, the Fit to Page button did not properly scale the image to a single page.
Bug fix: Importing a DXF or DWG as a background sketch image would scale improperly in some occasions and wouldn't overlap the region geometry. This typically occurred when text was present in the DXF or DWG.
Bug fix: In some cases GeoStudio could become unresponsive (hang) while importing regions using File - Import Regions.
Bug fix: Drawing a region on top of another region can sometimes cause errors in Verify.
Bug fix: Split Regions could fail in some valid cases.
Bug fix: In some cases where the Structured Grid mesh patterns are used GeoStudio could crash if the mesh is over constrained.
Bug fix: Trying to split a region with a mesh type of 'Rectangular grid of Quads' or 'Triangular grid of Quads / triangles' could fail.
Bug fix: When an analysis gets initial conditions from a specific time step of its parent, and the parent is changed so it has only a single time step, the child analysis would have an invalid time step selected but the Time combo box would disappear so there was no obvious way to correct the mistake.
Bug fix: In Draw Graph, the 'Select Time Steps' field might switch to 'Custom' unexpectedly.
Bug fix: In some cases, results did not load correctly when opening files solved by GeoStudio 2007 or earlier.
Bug fix: GeoStudio may incorrectly display the error message 'Unable to use results from file. The mesh is incompatible with this file' when attempting to load results from another analysis, even though the other analysis was solved using the same mesh.
Bug fix: GeoStudio may crash when saving a file.
