To get rid of this error, you can disable TSHistory with the command line option -ts_trajectory_use_history 0
<div class=""><br class="">
</div>
<div class="">or set up your TS with</div>
<div class=""><br class="">
</div>
<div class="">TSGetTrajectory(ts, &tj);</div>
<div class="">TSTrajectorySetUseHistory(tj, PETSC_FALSE);</div>
<div class=""><br class="">
</div>
<div class="">It is a known issue, but not the intended behavior for TSSetSaveTrajectory. I think TSHistory should be disabled by default in TS. It is actually disabled in the setup for TSAdjoint. So if you call TSAdjointSolve once, this error should not occur
in the following calls to TSSolve.</div>
