DMFieldShellEvaluateFVDefault#

Default finite-volume evaluation for a DMFIELDSHELL that samples at cell centroids using the coordinate DMField’s default quadrature and calls DMFieldEvaluate().

Synopsis#

#include "petscdmfield.h" 
PetscErrorCode DMFieldShellEvaluateFVDefault(DMField field, IS pointIS, PetscDataType type, void *B, void *D, void *H)

Not Collective

Input Parameters#

field - the DMField of type DMFIELDSHELL
pointIS - the IS of mesh cells at which to evaluate
type - PETSC_SCALAR or PETSC_REAL

Output Parameters#

B - cell-averaged values, or NULL
D - cell-averaged derivatives, or NULL
H - cell-averaged Hessians, or NULL

Note#

Intended to be registered as the FV evaluation callback via DMFieldShellSetEvaluateFV() when the shell only supplies a bulk DMFieldEvaluate() implementation.
