[petsc-users] DMPlex examples in parallel/3D?

[Mark Lohry]

I'm interested in trying DMPlex for a parallel 3D unstructured DG 
solver.  Is it appropriate for this, and is it considerably more work 
than for the simple DMDACreate3D examples? The manual example seems 
fairly clear on how to set up a mesh in serial, but does this play 
nicely with METIS for partitioning, and DMDA for parallel 
arrays/communication? I'm typically using CGNS files, so is 
DMPlexCreateCGNS working in parallel and appropriate for this?

Any examples/guidance related to this would be appreciated.
