PetscFEIntegrate

Produce the integral for the given field for a chunk of elements by quadrature integration

Synopsis

#include "petscfe.h" 
PetscErrorCode PetscFEIntegrate(PetscDS prob, PetscInt field, PetscInt Ne, PetscFEGeom *cgeom, const PetscScalar coefficients[], PetscDS probAux, const PetscScalar coefficientsAux[], PetscScalar integral[])

Not Collective

Input Parameters

• prob - The PetscDS specifying the discretizations and continuum functions

• field - The field being integrated

• Ne - The number of elements in the chunk

• cgeom - The cell geometry for each cell in the chunk

• probAux - The PetscDS specifying the auxiliary discretizations

• coefficientsAux - The array of FEM auxiliary basis coefficients for the elements

Output Parameter

• integral - the integral for this field

Developer Notes
