Reply To: ANSYS 2021 R1 INSTALLATION

[Rob]

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.
