[petsc-dev] reading gmsh into DMPlex

[Adrian Croucher]

hi

When I read the attached gmsh mesh using DMPlexCreateFromFile(), I get 
the following error:

[0]PETSC ERROR: --------------------- Error

This mesh was created using the meshio Python library 
(https://github.com/nschloe/meshio).

Gmsh itself seems to think it is valid. What is PETSc's problem with it?

It appears to be complaining about the $EndElements line not matching 
properly, but it looks ok to me.
