# DMTSSetRHSFunction

set `TS` explicit residual evaluation function into a `DMTS`

## Synopsis

    #include "petscts.h"
    PetscErrorCode DMTSSetRHSFunction(DM dm, TSRHSFunctionFn *func, void *ctx)

Not Collective

## Input Parameters

- dm - `DM` to be used with `TS`

- func - RHS function evaluation routine, see `TSRHSFunctionFn` for the calling sequence

- ctx - context for residual evaluation

## Note

`TSSetRHSFunction()` is normally used, but it calls this function internally because the user context is actually associated with the `DM`. This makes the interface consistent regardless of whether the user interacts with a `DM` or not. If `DM` took a more central role at some later date, this could become the primary method of setting the residual.
