The limitation occurs in two places:

  1) Calculating edges and faces: I only know how to do this for tri, tet,
quad, and hex. Give PETSC_FALSE to CreateFromCellList() and this error will
go away.
      You could also provide the information for interpolating prisms,
which would depend on how they are ordered when you read in cells.

  2) Even if you read them in, I have no geometric routines for prisms.

  Thanks,
