Anyone know how I can calculate principal stresses s1, s2 and s3 from
stress tensor using gmsh?
I saw there was a request for a plugin to do that. Was it implemented?
Yes: the principal stresses are the eigenvalues of the stress tensor, so
you can use Plugin(Eigenvalues) to compute them. If you also need the
principal directions, use Plugin(Eigenvectors).
