DMPlexComputeCellGeometryAffineFEM
Assuming an affine map, compute the Jacobian, inverse Jacobian, and Jacobian determinant for a given cell
Synopsis
#include "petscdmplex.h"
#include "petscfe.h"
PetscErrorCode DMPlexComputeCellGeometryAffineFEM(DM dm, PetscInt cell, PetscReal *v0, PetscReal *J, PetscReal *invJ, PetscReal *detJ)
Collective on DM
Input Arguments
| dm | - the DM
|
| cell | - the cell
|
Output Arguments
| v0 | - the translation part of this affine transform
|
| J | - the Jacobian of the transform from the reference element
|
| invJ | - the inverse of the Jacobian
|
| detJ | - the Jacobian determinant
|
Fortran Notes
Since it returns arrays, this routine is only available in Fortran 90, and you must
include petsc.h90 in your code.
