time_tolerance and sync_times

[hsheldon]

Does time_tolerance apply to sync_times, or is it only used at the beginning and end of the simulation? I'm having trouble with the solver not reaching sync_times exactly, then trying to take a tiny step to reach the next sync_time and failing to converge. Setting time_tolerance doesn't seem to make any difference.

Yes, it it applied in the TimeStepper object. The "timestep_tolerence" in the Executioner is applied to the TimeStepper here:

moose/framework/src/timesteppers/TimeStepper.C

Line 130 in ee00f87

if (!_sync_times.empty() && _time + dt + _timestep_tolerance >= (*_sync_times.begin()))

Ah, I needed timestep_tolerance, not time_tolerance! Thanks. It works now.

Ooops, sorry for setting you wrong @hsheldon

Glad it works, I didn't even notice the difference between your question and what I found. 😄
