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.
