Question #636692 on Yade changed:

Status: Open => Answered
Klaus Thoeni proposed the following answer:
The current implementation of the pFacet is based on gridConnections,
i.e., it is a discrete element with "internal contact forces/moments" in
its edges. The formulation is not continuum based as the FEM. You could
calculate the stresses from the "internal contact forces" but not sure
how accurate this is going to be. In terms of computational effort, I
think it would be the same. However, the pFacet should be more robust
for contact tracking, especially for sliding contacts.
