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.
