TSTrajectoryGetUpdatedHistoryVecs#
Get updated state and time-derivative history vectors.
Synopsis#
#include "petscts.h"
PetscErrorCode TSTrajectoryGetUpdatedHistoryVecs(TSTrajectory tj, TS ts, PetscReal time, Vec *U, Vec *Udot)
Collective on TSTrajectory
Input Parameters#
tj - the TS trajectory context
ts - the TS solver context
time - the requested time
Output Parameters#
U - state vector at given time (can be interpolated)
Udot - time-derivative vector at given time (can be interpolated)
Notes: The vectors are interpolated if time does not match any time step stored in the TSTrajectory(). Pass NULL to not request a vector. This function differs from TSTrajectoryGetVecs since the vectors obtained cannot be modified, and they need to be returned by calling TSTrajectoryRestoreUpdatedHistoryVecs().
