DMForestSetBaseCoordinateMapping#

Set a user-supplied mapping that is applied to the base DM’s coordinates when the forest computes coordinates for refined cells.

Synopsis#

#include "petscdmforest.h" 
#include "petscdm.h" 
#include "petscdmlabel.h" 
PetscErrorCode DMForestSetBaseCoordinateMapping(DM dm, PetscErrorCode (*func)(DM base, PetscInt coarsePoint, PetscInt dim, const PetscReal coordIn[], PetscReal coordOut[], PetscCtx ctx), PetscCtx ctx)

Logically Collective

Input Parameters#

dm - the DMFOREST
func - callback that maps reference coordinates to physical coordinates
ctx - optional application context passed through to func

Calling sequence of `func`#

base - the base DM of the forest
coarsePoint - the base-DM cell that owns the coordinate being mapped
dim - the coordinate dimension (at most 3)
coordIn - the input coordinate on the base DM
coordOut - the mapped coordinate to be written
ctx - optional application context
