DMPlexRefineRegularGetAffineTransforms

Gets the affine map from the reference cell to each subcell

Synopsis

#include "petscdmplextransform.h" 
PetscErrorCode DMPlexRefineRegularGetAffineTransforms(DMPlexTransform tr, DMPolytopeType ct, PetscInt *Nc, PetscReal *v0[], PetscReal *J[], PetscReal *invJ[])

Input Parameters

• cr - The DMPlexTransform object

• ct - The cell type

Output Parameters

• Nc - The number of subcells produced from this cell type

• v0 - The translation of the first vertex for each subcell

• J - The Jacobian for each subcell (map from reference cell to subcell)

• invJ - The inverse Jacobian for each subcell
