I put in code to force all fields to use the same quadrature by default
since many people had problems
with this. For some reason, it does not guess the quadrature for your mesh
correctly. You can turn this off
using

  -petscds_force_quad 0

  Thanks,

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