We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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.
