There was a rudimentary gui of sorts, and we were taught using that and maybe very minimal command line stuff (I did learn some “programming” for Matlab in a different class, but all of that knowledge is long gone), but I remember it being very unresponsive and buggy.
Or maybe I just sucked at it, though I’m generally very good with computers and intuitively figuring out how software is supposed to work. ANSYS was not intuitive lol. I just remember trying to make meshes and wanting to smash the PC.
