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

Input Parameters#

  • dm - the DMPLEX

  • cell - the cell

Output Parameters#

  • v0 - the translation part of this affine transform, meaning the translation to the origin (not the first vertex of the reference cell)

  • J - the Jacobian of the transform from the reference element

  • invJ - the inverse of the Jacobian

  • detJ - the Jacobian determinant
