This release includes bug fixes and enhancements for the TOUGH2 and TOUGH2-MP simulators.

Changes since PetraSim 5.1.1710 include:

• Fixed a bug in TOUGH2 that caused an access violation in models that used more than 4/5 of the maximum number of sources and sinks.
• Updated TOUGH2 binaries to have a limit of 50,000 sources/sinks and 1 million source/sink history pairs.
• TOUGH2-MP binaries now use a calculated (i.e. problem-specific) CG solver iteration limit.
• Fixed a bug in TOUGH2-MP that caused EOS2 to use the incorrect molecular weight for CO2 in mass calculations (44.0 instead of 18.016).
• Fixed a bug that prevented TOUGH2 simulations from starting when cell flow rates had been loaded from a file.

This release includes several fixes to the TOUGH-MP executables included with PetraSim. … Continue Reading

This release is a patch that prevents problems related to the latest ATI graphics card driver and PetraSim’s use of textures (e.g. top images). … Continue Reading

This release fixes two bugs related to the new flux-based boundary condition specification options. … Continue Reading

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 contour and wells.
  “Initial State and Production Analysis in a Layered Model“
• Fixed bug that caused a crash when changing to default Brine Data in EOS7R.
• Changed TMVOC/T2VOC CHEMP tab names to be consistent with TMVOC/T2VOC manuals.

This release fixes a bug related production boundary conditions in TOUGHREACT and improves the input file reader in TMVOC. … Continue Reading

This release fixes a bug in PetraSim’s Load Well Flow Rates feature and includes several other minor improvements. … Continue Reading

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.
