Additional Info: I opened the same file with the legacy ansys-mapdl-reader and the plotted result matches expectation (1st image above). I haven't been able to find any cause of why dpf-post is producing the 2nd image above. I will also mention that the node counts match in all readers, but dpf-post's element count is reduced by the number of missing elements. It's strange.

Hi @johonea4 , Thanks for finding this, please could you share the rst file? Thanks Ramdane
I can certainly supply more if needed. Please let me know.
Hi @johonea4, The issue was that the shell43 and shell63 elements (used in the provided file) were not supported. A fix is found and will be available for the next Ansys 2022 R1 release. @rlagha Thank you.
Hello. I'm having an issue when loading RST files with dpf post, and I believe the issue persists in dpf-core as well. When loading a verification test case RST file generated from Ansys 19 (Have checked prior versions with similar behavior) parts of the model are missing when doing a mesh.plot(). Below are images of what I'm expecting vs. what I get. Any insight? I am able to share the RST as well if wanted.
