DMSubDomainHookRemove

remove a callback from the list to be run when restricting a problem to subdomain DMs with DMCreateDomainDecomposition()

Synopsis

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMSubDomainHookRemove(DM global, PetscErrorCode (*ddhook)(DM dm, DM block, PetscCtx ctx), PetscErrorCode (*restricthook)(DM dm, VecScatter oscatter, VecScatter gscatter, DM block, PetscCtx ctx), PetscCtx ctx)

Logically Collective; No Fortran Support

Input Parameters

• global - global DM

• ddhook - function to run to pass data to the decomposition DM upon its creation

• restricthook - function to run to update data on block solve (at the beginning of the block solve)

• ctx - [optional] application context for provide data for the hooks (may be NULL)

Calling sequence of ddhook

• dm - global DM

• block - subdomain DM

• ctx - optional application function context

Calling sequence of restricthook

• dm - global DM

• oscatter - scatter to the outer (with ghost and overlap points) sub vector

• gscatter - scatter to sub vector values only owned locally

• block - subdomain DM

• ctx - optional application function context
