PetscFECreateCellGeometry

Populates the arrays in a PetscFEGeom for a single reference cell of a PetscFE.

Synopsis

#include "petscfe.h" 
PetscErrorCode PetscFECreateCellGeometry(PetscFE fe, PetscQuadrature quad, PetscFEGeom *cgeom)

Not Collective

Input Parameters

• fe - the PetscFE whose dual-space DM provides the reference cell

• quad - the quadrature at which to evaluate the geometry, or NULL to use the PetscFE’s own quadrature

Output Parameter

• cgeom - the PetscFEGeom populated with reference-cell coordinates, Jacobians, inverse Jacobians, and their determinants

Notes

This does not create cgeom, it allocates the arrays within one

Free the storage with PetscFEDestroyCellGeometry().
