DMMeshCreateExodus() will read in the mesh. SNES ex12 should then be able to
use that mesh. It is P1
Lagrange for Bratu, which is close. Let me know if you have trouble
modifying it.

What most experimenters take for granted before they begin their experiments
is infinitely more interesting than any results to which their experiments
lead.
