New question #658232 on Yade: https://answers.launchpad.net/yade/+question/658232
I aim to implement the Uniform Stress micro-scale boundary condition in Yade using the approach described in [1]. Eventually my goal is to implement an engine that does this seamlessly, along the lines of TriaxialStressController(). However, in the short term I was hoping to use PyRunner in a Yade script to demonstrate how this could work. I could use the triangulation done with TesselationWrapper() or FlowEngine(), to extract the surface boundary. The area vector for each boundary particle could then be calculated from the triangulated boundary surface. The hiccup for this short-term implementation is that I cannot seem to find a way to access the triangulation data in a Yade script. One approach I tried was to use TW.defToVtk() to write the data to a file, then read it and use vtkDataSetSurfaceFilter() to extract the surface. This approach was not only cumbersome, but stripped out any relationship the triangulation has with the DEM model since the particle numbers are not preserved in the .vtk file. My question is whether the triangulation data can be used in a Yade script, or is the triangulation only implemented internally for analysis and post-processing?
