TSEvaluateStep#

Evaluate the solution at the end of a time step with a given order of accuracy.

Synopsis#

#include "petscts.h"  
PetscErrorCode TSEvaluateStep(TS ts, PetscInt order, Vec U, PetscBool *done)

Collective

Input Parameters#

  • ts - time stepping context

  • order - desired order of accuracy

  • done - whether the step was evaluated at this order (pass NULL to generate an error if not available)

Output Parameter#

  • U - state at the end of the current step

Notes#

This function cannot be called until all stages have been evaluated.

It is normally called by adaptive controllers before a step has been accepted and may also be called by the user after TSStep() has returned.
