[petsc-dev] DMCreateSubDM error

[Blaise A Bourdin]

Hi,

I am building torture test for DMPlex with somewhat complicated dof layout. In some situations, DMCreateSubDM fails.

DMUAS has 3 fields corresponding to
U: corresponding to vector-valued P1 or P2 Lagrange FE, Sigma, vector-valued cell centered, and Alpha, same element type as U but scalar.
For Tri / Tet, P1 or P2, all is well, but with Quads / Hex and polynomial order 2, when trying to extract the DM for the (U,alpha) pair of fields, I get a "Nonconforming object sizes” error.

Try EXOTest12 -i TwoQuads.exo -order 2 for instance

I am attaching an code illustrating this behavior and three example meshes.

Regards,
Blaise
