TSSetEvaluationTimes#
sets the evaluation points. The solution will be computed and stored for each time requested
Synopsis#
#include "petscts.h"
PetscErrorCode TSSetEvaluationTimes(TS ts, PetscInt n, PetscReal *time_points)
Collective
Input Parameters#
ts - the time-stepper
n - number of the time points
time_points - array of the time points
Options Database Key#
-ts_eval_times <t0,…tn> - Sets the evaluation times
Notes#
The elements in time_points must be all increasing. They correspond to the intermediate points for time integration.
TS_EXACTFINALTIME_MATCHSTEP must be used to make the last time step in each sub-interval match the intermediate points specified.
The intermediate solutions are saved in a vector array that can be accessed with TSGetEvaluationSolutions(). Thus using evaluation times may
pressure the memory system when using a large number of time points.
