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.

This is mostly due to another issue: are you sweep geometry or simulaiton span and monitor field result? if so, the matrix does not work. YOu will need to use fixed mesh size and mesh points during the sweep.

If this does not resolve the issue, please give the screenshots and the error message.
