SNESSetDM#
Sets the DM
that may be used by some nonlinear solvers or their underlying preconditioners
Synopsis#
#include "petscsnes.h"
PetscErrorCode SNESSetDM(SNES snes, DM dm)
Logically Collective
Input Parameters#
snes - the nonlinear solver context
dm - the dm, cannot be
NULL
Note#
A DM
can only be used for solving one problem at a time because information about the problem is stored on the DM
,
even when not using interfaces like DMSNESSetFunction()
. Use DMClone()
to get a distinct DM
when solving different
problems using the same function space.
