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 on TS and DM

Input Parameters

	ts	- the ODE 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.

Level
