PetraSim 5.0.0820 (Beta)

August 20, 2010

This is an update for the PetraSim 5 beta release.

  • Added TOUGH2-MP support. The EOS3 module is included with this release.
  • TOUGH2-MP options have been added to the Simulation Parameters dialog.
  • TOUGHREACT EXEs have been rolled back to the build deployed with PetraSim 4.2. This fixes a convergence bug caused by compiler optimizations.
  • When switching EOS modules, variable format data will be reset. State variables may still be re-interpreted to invalid values.
  • Fixed a bug that caused PetraSim to fail to import old SIM files that did not contain a mesh.
  • A warning is now shown when creating a new mesh will destroy existing cell data.
  • Improved the performance of the tree view when working with large numbers of cells.
  • The Show Vectors UI component is now properly linked to vector visibility in the 3D results.
  • Fixed a bug that caused PetraSim to be locale-sensitive when selecting the decimal character for TOUGH2 input files (e.g. sometimes use commas instead of periods).


PetraSim 5.0.0716 (Beta)

July 16, 2010

This is an update for the PetraSim 5 beta release.

  • Fixed a bug that caused PetraSim to sometimes omit relative permeability data when generating the ROCKS record of the TOUGH2 input file. ROCKS records 1.1-3 are now always written.
  • Fixed a bug in the cell connection area calculation for RZ meshes.
  • PetraSim now clamps the maximum number of GOFT entries at 100 this matches the TOUGH2 specification.
  • Models loaded from PetraSim v4 SIM files will now use less memory.
  • Fixed a bug that caused PetraSim to crash when starting a TOUGH2 simulation if a cell had a BC specified using a table.
  • Fixed a bug that caused incorrect INCON values to be written for TMVOC simulations that used a gas/NAPL or three-phase specification format.
  • Fixed a bug that caused TMVOC models loaded from v4 SIM files to lose BC data.
  • Improved 3D results performance when using a background images.


PetraSim 5.0.0628 (Beta)

June 28, 2010
This is a minor update for the PetraSim 5 beta release. A Select Cells action is now available on the context menu for regions, layers, and wells. This action will select all cells in the element. Fixed a bug that occured when importing old models that contained wells. Well cell IDs will will no longer be increased ... Read More...

PetraSim 5.0.0624 (Beta)

June 23, 2010

This version is a major update to PetraSim 4. All users are encouraged to work though the short Getting Started guide on the PetraSim Resources page to learn how some of the new features operate.

New features in PetraSim 5 include:

  • The 2D cell editor has been replaced by cell editing in the main 3D view.
  • Z divisions are now controlled by layers, making it easier to work with stratigraphy.
  • Polygonal (Voronoi) meshes are now supported.
  • Polygonal boundaries and boundary editing is now supported.
  • Many major changes “under the hood” which make PetraSim faster and more reliable.
  • Time history plots of accumulated well quantities are now available.
  • The Run dialog now includes a Log tab which shows selected simulator output.
