DMPlexComputeCellGeometryAffineFEM

Assuming an affine map, compute the Jacobian, inverse Jacobian, and Jacobian determinant for a given cell

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexComputeCellGeometryAffineFEM(DM dm, PetscInt cell, PetscReal *v0, PetscReal *J, PetscReal *invJ, PetscReal *detJ)
Collective on DM Many br

Input Arguments

dm - the DM Many br
cell - the cell Many br

Output Arguments

v0 - the translation part of this affine transform Many br
J - the Jacobian of the transform from the reference element Many br
invJ - the inverse of the Jacobian Many br
detJ - the Jacobian determinant Many br

Many br

Fortran Notes

Since it returns arrays, this routine is only available in Fortran 90, and you must Many brinclude petsc.h90 in your code. Many br
