Hi Kim,

That is true, an auto shutoff min of 1e-05 works for most cases, but typically for resonators we have seen that you might need lower values (1e-06, 1e-07). Unfortunately, there is no way to predict that. How the energy decays over the simulation time is very spefic to the geometry and the source conditions, and requires a bit of trial and error to get to the right value.
