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.

This screencast covers a method that can be used to build a 3D model in Google SketchUp, and then export the geometry for use in PyroSim using a SketchUp DXF/STL Export Plug-in.

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 is a short demonstration of using a thin obstruction with ‘fan’ surface properties applied to each side to pull gasses from one ‘room’ to another.

We just finished a round of optimization and now we have the data to show that the upcoming version of Pathfinder will be an improvement both in speed and in memory consumption. … Continue Reading
