TSSetStepNumber#
Sets the number of steps completed.
Synopsis#
#include "petscts.h"
PetscErrorCode TSSetStepNumber(TS ts, PetscInt steps)
Logically Collective on TS
Input Parameters#
ts - the TS context
steps - number of steps completed so far
Notes#
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.
