PetraSim 5.1.1416

February 16, 2011

This release fixes a bug related production boundary conditions in TOUGHREACT and improves the input file reader in TMVOC. Read More...

PetraSim 5.1.1408

February 8, 2011

This release fixes a bug in PetraSim's Load Well Flow Rates feature and includes several other minor improvements. Read More...

PetraSim 5.1.1402

February 2, 2011
This release fixes a TOUGHREACT input file format error. In models that contained more than one linear Kd zone, PetraSim was omitting the zone terminating asterisk – causing TOUGHREACT to halt prematurely. This update corrects the formatting error, allowing TOUGHREACT models with multiple linear Kd zones.  Read More...

PetraSim 5.1.1320

January 21, 2011

This release changes Line Plots and fixes a problem in 3D Results that prevented vectors from appearing on slice planes. This release also includes fixes to the TOUGH2 input file writer. Read More...

PetraSim 5.1.1303

January 3, 2011
This release fixes a bug in PetraSim’s input file writer. Changes since PetraSim 5.1.1215 include: When creating simulator input files, earlier versions of PetraSim 5.1 used the comma character as a decimal separator in some locales. This bug prevented simulations from running in these locales. PetraSim now uses a period as the decimal character in all locales ... Read More...

PetraSim 5.1.1215

December 15, 2010
This is an update release for PetraSim 5. This release adds support for MINC simulations, and includes several important bug fixes. Changes since PetraSim 5.0.0928 include: PetraSim can now run TOUGH2 and TOUGH2-MP with MINC enabled. Improved fixed-width number rendering in PetraSim to add several digits of precision when writing input files and improve readability. Improved the performance of ... Read More...

Five Spot Demo

November 23, 2010

This video demonstrates input, execution, and analysis of the 5-Spot Geothermal Production/Injection example presented in the TOUGH2 User's Guide. PetraSim is a graphical interface for TOUGH2, TOUGH2-MP, T2VOC, TMVOC, TOUGHREACT, TOUGH-Fx/HYDRATE, and TETRAD. These simulators are recognized for their powerful simulation capabilities involving fluid flow and heat transfer in porous and fractured media.

PetraSim 5.0.0928

September 28, 2010

This is the first official release of PetraSim 5. Changes since PetraSim 5.0.0907 (RC1) include:

  • Increased the FOFT/GOFT/COFT cell limit in TOUGH2-MP to 5,000.
  • The mesh cell limit in all TOUGH2 and TOUGHREACT simulators has been raised to 99,999. Other new limits include: 300,000 connections, 100,000 time history pairs, and 5000 source/sink cells.
  • In TOUGHREACT, the Advanced Solution Controls now contains an option to switch between TOUGHREACT v1.0 and v1.2
  • Fixed a bug that caused SAVE file cell entries to be skipped when a primary variable value was negative.
  • Fixed a bug that prevented PetraSim from using over 99 materials.
  • Fixed a bug that caused 2D plots to display incorrect vector results data.
  • TOUGHREACT chemical zone data can now be specified at the layer level.
  • The status bar now displays the number of active mesh cells.
  • In the 3D view, when cells are showing, data for the cell that is currently under the mouse pointer is displayed (e.g. coordinates, current coloring value).
  • Fixed memory leak that occurred during model creation and when viewing 3D Results.
