TSSetExactFinalTime#
Determines whether to adapt the final time step to match the exact final time, interpolate solution to the exact final time, or just return at the final time TS
computed.
Synopsis#
#include "petscts.h"
PetscErrorCode TSSetExactFinalTime(TS ts, TSExactFinalTimeOption eftopt)
Logically Collective
Input Parameters#
ts - the time-step context
eftopt - exact final time option
TS_EXACTFINALTIME_STEPOVER - Don't do anything if final time is exceeded
TS_EXACTFINALTIME_INTERPOLATE - Interpolate back to final time
TS_EXACTFINALTIME_MATCHSTEP - Adapt final time step to match the final time
Options Database Key#
-ts_exact_final_time <stepover,interpolate,matchstep> - select the final step at runtime
Note#
If you use the option TS_EXACTFINALTIME_STEPOVER
the solution may be at a very different time
then the final time you selected.
