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.

If you're remeshing can you check you've not added too many cells to one node? However, with 80k nodes I'd not run on more than 1, possibly 2 cores. The overhead for that number of partitions may well far exceed the benefit from having more compute power available.Â
