[Paraview] Displacements

[GeorgeP S]

Yes that might be the case! I am trying to open the attached state file to
see the example
but  it seems my version of paraview (5.5.2 Windows) , crashes when loading.
I am downloading an earlier version that might work.

Thank you,
Salachoris Georgios Panagiotis
