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 Kawshik,

At this point it is hard to say if this is expected or if there is an issue. In some devices, it can take a long time for the energy in the simulation domain to decay. What is the mesh accuracy that you are using? As a starting point I will recommed you to reduce the mesh accuracy to 1 or 2. Then increase the simulation time by 10 times, to see if you are able to reach the auto shutoff level.

Let me know what happens. 

Regards,
