# 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.
