PetraSim: Internal regions with DXF geometry from SketchUp.

March 30, 2011

We have posted a short video showing how to create DXF files in SketchUp and then use them to subdivide a PetraSim model into geometric regions. The demo shows how to create a cylinder inside a rectangular model and assign material properties to the cylinder.


PetraSim 5.1.1524

March 24, 2011
This release adds the capability to specify surface injection and production (source/sink) using flux. The specified flux is multiplied by the projected area on the XY plane to calculate flow. Changes since PetraSim 5.1.1416 include: New capability to specify surface injection and production flux. Added new TOUGH2 example that demonstrates natural state and production analyses using a surface ... Read More...

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.


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.


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.


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.
