Robert Caulk proposed the following answer:
Hello,
Thanks a lot for the clear description and the minimal working example
:-).
>FWIW, The fact that et is ignored is mentioned in the documentation for
Law2_ScGeom_ViscElPhys_Basic, but the fact that you get elastic behavior
if et is omitted is not.
Can you please link to where it says this? I cannot see it.
I admit I have not used this law but looking at the source code, et is
used to compute cs and ks [1], which are both used to compute the torque
[2].
Possible reasons you see no effect:
Your frictionAngle in your script is zero which might mean you never reach [3].
It is not immediately apparent that you would activate any shear in your
example script.
Cheers,
Robert
