How to access results from a rstp-file using dpf?

[bchocholaty]

Is there a way to access results from a rstp-file? The rstp-file results from a prestressed modal analysis which uses perturbation analysis.

For rst-files I do the following, which works nicely:

model = dpf.Model(rst_file)
disp = model.results.displacement.on_all_time_freqs.eval()

However, if I do the same for file.rstp, I get the following error:

ansys.dpf.gate.errors.DPFServerException: MeshProvider:5<-meshes_provider:6<-Operator(s) (mapdl::rstp::MeshProvider) does not exists in the registry !
