Hi @knepley,

What mesh formats, other than Gmsh and Exodus, can PETSc currently read? Is there any documentation available for this?

Thanks.

Thyagi,

While you are waiting for the definitive response from Matt, have a look at the DMPLEX documentation here and, particularly, all of the DMPLEXcreate_____ functions. That should give you the broad sense of what is possible. Matt can tell you how well each one works.

Following the Petsc4py example, I was able to create dmplex from .mesh file (medit format).
