[petsc-users] DMPlex higher order elements

I created an unstructured tri6 mesh in Cubit and am trying to read it into
PETSc using DMPlexCreateFromFile. However, when I do PETSc gives me an
error that it doesn't support this type of element.
I know my PETSc install has Exodus II support because by giving a different
Exodus mesh file with Tri3 elements works just fine. I've attached the
Exodus mesh generated by Cubit. I can open up the mesh file in Paraview
just fine and it does appear to be valid (it has 2 elements approximating a
quarter circle wedge).
Here's the error message:
