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