DMFieldShellSetEvaluateFV

Register the routine that evaluates a DMFIELDSHELL as cell averages over a set of mesh cells.

Synopsis

#include "petscdmfield.h" 
PetscErrorCode DMFieldShellSetEvaluateFV(DMField field, PetscErrorCode (*evaluateFV)(DMField field, IS is, PetscDataType dtype, void *B, void *D, void *H))

Logically Collective

Input Parameters

• field - the DMField of type DMFIELDSHELL

• evaluateFV - the FV evaluation callback

Calling sequence of evaluateFV

• field - the DMField of type DMFIELDSHELL

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

• dtype - PETSC_SCALAR or PETSC_REAL

• B - array of cell-averaged field values, or NULL

• D - array of cell-averaged field derivatives, or NULL

• H - array of cell-averaged field Hessians, or NULL

Note

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