Description of the bug

When I use CPT212 elements the stress and strain arrays are empty. When I repeat the same steps with a simulation using plane182 elements everything works as expected.

Steps To Reproduce

Perform an analysis with CPT212 element and save the results to file.rst
from ansys.dpf import post
sol = post.load_solution('file.rst')
s = sol.stress()
s.xx[0].data

DPFArray([], dtype=float64)

As I think the support for CPT elements is not implemented yet, what is the best way to postprocess results?
I don't understand if using mapdl.post_processing is also impossible for these elements or if I'm doing something wrong. Right now, I just need to access pressure DOF between load steps for certain nodes. I can get do it using mapdl.get but it's slow.
