DMSlicedSetBlockFills#

Sets the fill pattern in each block for a multi-component problem of the matrix returned by DMSlicedGetMatrix().

Synopsis#

#include "petscdmsliced.h" 
PetscErrorCode DMSlicedSetBlockFills(DM dm, const PetscInt *dfill, const PetscInt *ofill)

Logically Collective

Input Parameters#

sliced - the DM object
dfill - the fill pattern in the diagonal block (may be NULL, means use dense block)
ofill - the fill pattern in the off-diagonal blocks

Note#

This only makes sense for multicomponent problems using scalar matrix formats (AIJ). See DMDASetBlockFills() for example usage.
