<div dir="ltr"><div dir="ltr">Before your pull request merged to main, I copied your change to my local /src/dm/impls/plex/plexgmsh.c to test pyramids.<br><br>Loading DMPlex with the mesh including pyramids works okay, but printing out the solution field to .vtk or .vtu format causes a problem with "Unknown Cell Type Error" from post-processing tools (such as tecplot or paraview).<br><br>I had a look at /src/dm/impls/plex/plexvtk.c the function, DMPlexVTKGetCellType_Internal() seems not explicitly including a cellType marker for prism and pyramids. Probably, "VTK_WEDGE" is prism with triangular base, but still, there seems no pyramids marker. <br><br>Thanks,<br></div><br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><br>On Wed, Jul 13, 2022 at 11:18 AM Mike Michell <<a href="mailto:mi.mike1021@gmail.com" target="_blank">mi.mike1021@gmail.com</a>> wrote:<br></div><div dir="ltr"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr">Attached is a mixed mesh file that I am testing.
