Hi Torsten!

Look at the SfePy Primer [1], specifically the post-processing section. In short, you need to define a function ('post_process_hook' option in input file) that computes derived quantities from the computed variables (e.g. strain or stress from displacements).

Let us know how it goes.

Cheers, r.

Hallöchen!

I used linear_elasticity.py as a starting point for simulating stress in thin silicon layers. My manual meshing worked, and the displacements seem to be calculated properly. However, how do I get the stress in each element? I need it for determining where the layer will break.

The original node positions of the mesh are totally relaxated (no tension anywhere).

Tschö, Torsten.
