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