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 Zhaokai,

In general, the thermal envelop calculation in Lab is heavy and takes a lot of time. That is not out of the ordinary. About the numerical error, we would have to inspect the model. Please reach out through the customer portal and create a support request.

 

Kind regards,
