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 on TS

Input Arguments

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 Arguments

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.
