DMPlexComputeCellGeometry

Compute the Jacobian, inverse Jacobian, and Jacobian determinant for a given cell

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexComputeCellGeometry(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.
