Hi Robert,

this helped a lot. It's the same issue in examples/linear_elasticity/its2D_interactive.py

best, JonnyB

Hi Fred,

this is caused by the commit 61ec2878cff85daf141c6f4a6441074ead2ddbe8 - the change was necessary in order to be able to use different material definitions in post-processing.

So, if the material 'm' is defined in the problem, add "copy_materials=False" to the pb.evaluate() call, or, if it is a new material. pass it explicitely: pb.evaluate(..., m=m).

Does it help?
