Hi,

I'm learning PETSc DMPlex module recently. A problem occurs to my PETSc when I'm using DMPlexCreateExodusFromFile() to import a mesh file. I've tried to generate a mesh with Pointwise and ICEM, but both mesh files can't be input to PETSc. The Error code is :

I am not familiar with Pointwise or ICEM. The problem here is that the element type 'TRIANGLE' is not recognized by PETSc, and it does not appear in the ExodusII documentation that I am using: https://gsjaardema.github.io/seacas-docs/html/element_types.html It is also not used by Cubit/Trellis. I am not sure why your program is making non-standard ExodusII files. Thanks, Matt

Looking forward to your reply!
