PetscDualSpaceGetUniform
Whether this dual space is uniform
Synopsis
#include "petscfe.h"
PetscErrorCode PetscDualSpaceGetUniform(PetscDualSpace sp, PetscBool *uniform)
Not collective
Input Parameters
sp -A dual space
Output Parameters
uniform -PETSC_TRUE if (a) the dual space is the same for each point in a stratum of the reference DMPlex, and
(b) every symmetry of each point in the reference DMPlex is also a symmetry of the point's dual space.
Note: all of the usual spaces on simplex or tensor-product elements will be uniform, only reference cells
with non-uniform strata (like trianguar-prisms) or anisotropic hp dual spaces will not be uniform.
