PetraSim - interactive model creation for advanced flow, transport and heat transfer models. A preprocessor and postprocessor for TOUGH2, T2VOC, TMVOC, TETRAD and TOUGHREACT
New Features 

New Features in Version 3


  • ToughFX/HYDRATE - You can use PetraSim with the ToughFX/HYDRATE simulator to model subsurface CH4-hydrate deposits.
  • ECO2 Now Available - Model water, NaCl, and CO2 flow with this new EOS module.
  • Extra Cells - You can introduce boundary conditions using extra, non-grid cells. This option is available on the Model menu.
  • Meshmaker RZ Grids - You can use the meshmaker input style to create RZ grids.
  • Improved Progress Monitor - The simulation progress monitor now shows a graph of the current time step size and other simulation metrics.
Interface for adding extra boundary condition cells using a spreadsheet interface  

  • Saved 3D Views - You can save and recall up to four custom 3D viewpoints on a model. Options to save and restore saved views can be found in the view menu.
  • Image Overlays - You can overlay images on your models in the 3D views. This option is on the View menu.
  • 3D Labels - You can attach text labels to 3D points. These labels appear in the 3D views. Labels are automatically added to the model boundaries and wells. Labels can be edited in the Labels dialog, available through the Model menu.
  • Screen Capture Option - You can create high-resolution screen shots of your model and 3D results data. This option is on the File menu.
Create normal and RZ grids using the TOUGH2 MeshMaker tool  

  • 2D Editor Performance - The performance of the 2D editor has been improved.
  • Cell IDs - Cell IDs can now be shown in the 2D editor. This option is on the View menu.
  • Axis Scaling - You can now define a axis scale factor in the 3D views. This is often useful for 1D problems. This feature affects visualization only.
  • RP and CP Graphs - Your relative permeability and capillary pressure settings are now automatically shown in a graph.
The new program monitor allows you to track model time and time step size  

  • Better RP and CP Defaults - The relative permeability and capillary pressure functions are now initialized with reasonable defaults.
  • Find Cells by Name or ID - You can now search for cells by name or ID number in the 2D editor. The search field is in the upper-right hand corner of the 2D grid editor.
  • Error Recovery - PetraSim will now attempt to save a copy of the current model if forced to exit unexpectedly.
New visualization tools include 3D maps and labels
