DMPlexCellRefinerGetAffineFaceTransforms

Gets the affine map from the reference face cell to each face in the given cell

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexCellRefinerGetAffineFaceTransforms(DMPlexCellRefiner cr, DMPolytopeType ct, PetscInt *Nf, PetscReal *v0[], PetscReal *J[], PetscReal *invJ[], PetscReal *detJ[])

Input Parameters

cr - The DMPlexCellRefiner object
ct - The cell type

Output Parameters

Nf - The number of faces for this cell type
v0 - The translation of the first vertex for each face
J - The Jacobian for each face (map from original cell to subcell)
invJ - The inverse Jacobian for each face
detJ - The determinant of the Jacobian for each face

Note: The Jacobian and inverse Jacboian will be rectangular, and the inverse is really a generalized inverse.
