# TSSetUp

Sets up the internal data structures for the later use of a timestepper.

## Synopsis

    #include "petscts.h"
    PetscErrorCode TSSetUp(TS ts)

Collective

## Input Parameter

- ts - the `TS` context obtained from `TSCreate()`

## Note

For basic use of the `TS` solvers the user need not explicitly call `TSSetUp()`, since these actions will automatically occur during the call to `TSStep()` or `TSSolve()`. However, if one wishes to control this phase separately, `TSSetUp()` should be called after `TSCreate()` and optional routines of the form TSSetXXX(), but before `TSStep()` and `TSSolve()`.
