TSPseudoSetVerifyTimeStep#
Sets a user-defined routine to verify the quality of the last timestep.
Synopsis#
#include "petscts.h"
PetscErrorCode TSPseudoSetVerifyTimeStep(TS ts, PetscErrorCode (*dt)(TS ts, Vec update, void *ctx, PetscReal *newdt, PetscBool *flag), void *ctx)
Logically Collective
Input Parameters#
ts - timestep context
dt - user-defined function to verify timestep
ctx - [optional] user-defined context for private data for the timestep verification routine (may be
NULL)
Calling sequence of func#
ts - the time-step context
update - latest solution vector
ctx - [optional] user-defined timestep context
newdt - the timestep to use for the next step
flag - flag indicating whether the last time step was acceptable
Note#
The routine set here will be called by TSPseudoVerifyTimeStep()
during the timestepping process.
