TSInterpolate#

Interpolate the solution computed during the previous step to an arbitrary location in the interval

Synopsis#

#include "petscts.h"  
PetscErrorCode TSInterpolate(TS ts, PetscReal t, Vec U)

Collective

Input Parameters#

  • ts - time stepping context

  • t - time to interpolate to

Output Parameter#

  • U - state at given time

Developer Notes#

TSInterpolate() and the storing of previous steps/stages should be generalized to support delay differential equations and continuous adjoints.
