Synopsis#

#include "petscdmshell.h"  
PetscErrorCode DMLocalToLocalBeginDefaultShell(DM dm, Vec g, InsertMode mode, Vec l)

Input Parameters#

  • dm - DMSHELL

  • g - the original local vector

  • mode - InsertMode

This is not normally called directly by user code, generally user code calls DMLocalToLocalBegin() and DMLocalToLocalEnd(). If the user provides their own custom routines to DMShellSetLocalToLocal() then those routines might have reason to call this function.
