hello all,  
I am using open-source software YADE to do some simulations. I want to get the strain-field.

theoretically, this software can export the data and use Paraview to visualization the data. but now the software is not fully installed. so I can just export the displacement. right now I need to use the displacement filed to get the strain field. but I have no idea how to get this in Paraview. should I use python in Paraview, is there anyone can give me some suggestions.  
best,
