Description of the bug

Stress (as well as other) results are not extracted on beam elements.

Steps To Reproduce

from ansys.dpf import post

file_path = "post_beam_result_01.rst"

simulation = post.StaticMechanicalSimulation(file_path)
seqv = simulation.stress_eqv_von_mises_nodal()
print(seqv._fc[0])

output

DPF stress_1.s_eqv Field
  Location: Nodal
  Unit: in^-1*slinch*s^-2
  0 entities
  Data: 1 components and 0 elementary data

RST file to run the script: post_beam_result_01.zip

@janvonrickenbach I guess the read_beams pin need to be set for the result operators supporting it?

[janvonrickenbach]

@FedericoNegri Is it really expected that we have stress results for beams? With #778 displacement results are available for the full model as well as on the skin.

Yeah I think we'd anyway need special treatment for beam stresses, either show it separately or do beam expansion. Closing this one.
