PetscFEIntegrateBd

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

Synopsis

#include "petscfe.h" 
PetscErrorCode PetscFEIntegrateBd(PetscDS prob, PetscInt field, void (*obj_func)(PetscInt, PetscInt, PetscInt, const PetscInt[], const PetscInt[], const PetscScalar[], const PetscScalar[], const PetscScalar[], const PetscInt[], const PetscInt[], const PetscScalar[], const PetscScalar[], const PetscScalar[], PetscReal, const PetscReal[], const PetscReal[], PetscInt, const PetscScalar[], PetscScalar[]), PetscInt Ne, PetscFEGeom *geom, 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

• obj_func - The function to be integrated

• Ne - The number of elements in the chunk

• geom - The face geometry for each face in the chunk

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

• 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

The function name begins with PetscFE and yet the first argument is PetscDS and it has no PetscFE arguments.
