DMPlexRemapGeometry#

This function maps the original DM coordinates to new coordinates.

Synopsis#

#include "petscdmplex.h"   
#include "petscfe.h"       
PetscErrorCode DMPlexRemapGeometry(DM dm, PetscReal time, void (*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[], PetscInt, const PetscScalar[], PetscScalar[]))

Not Collective

Input Parameters#
