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