TSPseudoVerifyTimeStep#

Verifies whether the last timestep was acceptable.

Synopsis#

#include "petscts.h"   
PetscErrorCode TSPseudoVerifyTimeStep(TS ts, Vec update, PetscReal *dt, PetscBool *flag)

Collective

Input Parameters#

  • ts - timestep context

  • update - latest solution vector

Output Parameters#

  • dt - newly computed timestep (if it had to shrink)

  • flag - indicates if current timestep was ok

Notes#

The routine to be called here to compute the timestep should be set by calling TSPseudoSetVerifyTimeStep().
