Dear getfem-users,
I have started using getfem recently to work on few contact problems between elastic bodies.
I am able to solve few simple cases and I am able to compute displacement (u) and Von-Mises/Tresca values on my mesh nodes.
The problem I am facing is that I have to calculate pressure at the mesh points and for that I believe I need the stress tensor values at these discrete mesh points. Could someone please guide me or tell me how to get the value of these variables. I went through the documentation and checked everywhere but I couldn't find a way to calculate stress tensor/pressure.
Thanks a lot.
