TSSetDM#

Sets the DM that may be used by some nonlinear solvers or preconditioners under the TS

Synopsis#

#include "petscts.h"  
PetscErrorCode TSSetDM(TS ts, DM dm)

Logically Collective

Input Parameters#

  • ts - the TS integrator object

  • dm - the dm, cannot be NULL

Notes#

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 DMTSSetIFunction(). Use DMClone() to get a distinct DM when solving different problems using the same function space.
