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.

You'd need University IT to download & install an older copy, that's available on the Customer side of the ansys.com site. As a Student you won't have access, your Prof should. That should then run on a University machine that's connected to the licence server. There is no build of Student available older than 2023R2. 

I would be surprised if an element type had been retired in that way, I'll check.Â
