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 on TS

Input Argument

ts - time stepping context
t - time to interpolate to

Output Argument

U -state at given time

Notes

The user should call TSSetRetainStages() before taking a step in which interpolation will be requested.

Developer Notes

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

Keywords

TS, set
