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.

Numerical simulation of air flow during tunnel advance.

Investigation of air and LNAPL entrapment in the Partially Saturated Fringe (PSF – the region bounding the water table in the groundwater system) in heterogeneous systems in the presence of a rising water table.

This is an update for the PetraSim 5 beta release.

• Added remaining TOUGH2-MP EOS support (simulator executables).
• The TOUGH2-MP EOS9 executable is not currently recommended. It originated from a different code base and has not yet been made consistant with the other simulator versions.
• Material can now be specified by layer (in addition to global, region, and cell).
• Fixed a bug in the mesh creator that occurred when using an auto-fit boundary.
• Fixed a bug in the Polygonal mesh creator UI that sometimes caused the cell count estimate to be negative.
• Fixed a bug in the layer manager that prevented color and top/base changes from correctly propagating through the event system.
• The Tree View will no longer become too thin when PetraSim is run at 800×600 resolution.
