Geo 18.1 Build 5 Patches: New Features

Geo 18.1 Build 5 Patches : New Features - Safe

• Simple mesh specification added to Graphical Input view's features.
• Better Undo facility - copes with undoing line addition / delete / split (but not simply editing) and region creation / deletion
• Button added to generate "standard restraints" along bottom of mesh and down left and right vertical edges
• Group selection and deletion of lines implemented
• Splitting or deleting a line correctly deletes any subregions connected to the changed/removed line
• Link to "Online demos" added to Help menu

Geo 18.1 Build 5 Patches: Fixes

Geo 18.1 Build 5 Patches: Fixes - Safe

• Mesh generation points deleted on opening file, if had been pasted from Excel

Geo 18.1 Build 5 : New Features

Geo 18.1 Build 5 : New Features - Safe

• Standard sets of units (SI, kN-m, kip-ft and kip-in) may be selected via the Units and Preferences dialog.
• So as to help users to ensure that they are running the latest software a new version checking system has been implemented. This compares each executable file installed locally with the set that Oasys identifies as being the 'current' version. (The comparison is carried out locally; no data is transmitted to Oasys.) Executables for which updates are available are highlighted. Updates may then be downloaded from the Program's Downloads page on the Internet. This system enables rapid delivery of bug fixes and, occasionally, minor enhancements.
• Graphical input has been revised and now includes:
  • switching between node and element selection (without having to change the view shown);
  • automatic switch between single and group selection;
  • setting restraints on mesh lines before generating;
  • graphical entry of seepage restraints; and
  • better graphical input of pressure loads.
• In the graphical output:
  • multi-graph plots on the same axis have been reinstated; and
  • an envelope plotting facility has been added to the graph plot view.

Geo 18.1 Build 5 : Fixes

Geo 18.1 Build 5 : Fixes - Safe

• The cohesion component of strength of ubiquitous joint needs to be converted correctly for the analysis.
  [NCR 19] (Fixed 06 April 2006)
• Equation related to Detailed Processes, Stress-Strain Models and linear elastic materials to be corrected in the manual.
  [NCR 20] (Fixed 05 May 2006)
• Add note on undrained analysis to the manual.
  [NCR 21] (Fixed 05 May 2006)
• Equation to be corrected in the manual related to permeability data, the term "gradient of k".
  [NCR 22] (Fixed 05 May 2006)
• Use of undrained materials in a steady state run to be added to the help file / manual.
  [NCR 23] (Fixed 22 May 2006)
• Node results in the tabulated and graphical output, the reported applied loads should be cumulative loads.
  [NCR 24] (Fixed 22 May 2006)

Geo 18.1 Build 5 : Fixes - Brick

• Version checking fails to identify the current version correctly.
  [NCR 25] (Fixed 26 May 2006)(Released 30 May 2006 in Brick.exe 18.1.6.0)

Finite Elements: Outstanding Bugs

Outstanding Bugs - Safe

• Safe may crash on analysis of consolidation run (possibly only on W2000 PCs).
  [NCR 1]
• Major difference in the piezo head contour plots between 17.8 and 18.0 to run a problem involving well.
  [NCR 3]
• Manual wrong for undrained & suction limits.
  [NCR 9]
• Non-symmetrical results obtained for tunnel problem with symmetrically placed springs.
  [NCR 10]
• Scaling problems for plotting the stresses, bending moments etc.. and re-run the analyses may cause slightly differing results from old version
  [NCR 11]
• Change some of the permeability parameters and re-run the analysis may cause unexpected crash.
  [NCR 12]
• Graphical input - auto generation doesn't always complete (last region omitted) - workaround : select required lines and create manually
  [NCR 30]

Outstanding Bugs - Brick

• None.
