DMPlexSetAdjacencyUser

Define adjacency in the mesh using a user-provided callback

Synopsis

#include "petscdmplex.h"   
#include "petscdmlabel.h"  
PetscErrorCode DMPlexSetAdjacencyUser(DM dm, PetscErrorCode (*user)(DM, PetscInt, PetscInt *, PetscInt[], void *), void *ctx)

Input Parameters

• dm - The DM object

• user - The user callback, may be NULL (to clear the callback)

• ctx - context for callback evaluation, may be NULL

Notes

The caller of DMPlexGetAdjacency() may need to arrange that a large enough array is available for the adjacency.

Any setting here overrides other configuration of DMPLEX adjacency determination.
