TSSetStepNumber#

Sets the number of steps completed.

Synopsis#

#include "petscts.h"  
PetscErrorCode TSSetStepNumber(TS ts, PetscInt steps)

Logically Collective

Input Parameters#

  • ts - the TS context

  • steps - number of steps completed so far

Note#

For most uses of the TS solvers the user need not explicitly call TSSetStepNumber(), as the step counter is appropriately updated in TSSolve()/TSStep()/TSRollBack(). Power users may call this routine to reinitialize timestepping by setting the step counter to zero (and time to the initial time) to solve a similar problem with different initial conditions or parameters. Other possible use case is to continue timestepping from a previously interrupted run in such a way that TS monitors will be called with a initial nonzero step counter.
