DMFieldShellSetEvaluateFE

Register the routine that evaluates a DMFIELDSHELL at finite-element quadrature points over a set of mesh points.

Synopsis

#include "petscdmfield.h" 
PetscErrorCode DMFieldShellSetEvaluateFE(DMField field, PetscErrorCode (*evaluateFE)(DMField field, IS is, PetscQuadrature quad, PetscDataType dtype, void *B, void *D, void *H))

Logically Collective

Input Parameters

• field - the DMField of type DMFIELDSHELL

• evaluateFE - the FE evaluation callback

Calling sequence of evaluateFE

• field - the DMField of type DMFIELDSHELL

• is - the IS of mesh cells on which to evaluate the field

• quad - the reference-cell PetscQuadrature supplying the evaluation points

• dtype - PETSC_SCALAR or PETSC_REAL

• B - array of field values at each quadrature point, or NULL

• D - array of field reference derivatives at each quadrature point, or NULL

• H - array of field reference Hessians at each quadrature point, or NULL

Note

If the shell only supplies a generic DMFieldEvaluate() via DMFieldShellSetEvaluate(), pass DMFieldShellEvaluateFEDefault() here.
