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
Input Parameters#
tj - the
TSTrajectorycontextts - the
TSsolver contexttime - 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().
