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.

Yes, there is also the problem of too small a time step with higher order elements (producing temperature undershoot.)  You might consider using linear, lower order, elements to avoid that issue.  I don't know a rule of thumb for setting the time step to capture the correct thermal shock surface temperature.  You could determine it experimentally with a test model.
