I was sent a document with the URL in my initial post by our Ansys rep. That was after I asked about network licensing. They pointed me to this forum for questions. I haven't downloaded anything yet because I'm trying to find out if there are newer versions of the network licensing software or if the old versions work on something more modern and supportable.
I'm the IT person setting up this license server. I won't be using LS-DYNA, so I don't know the exact versions, but my assumption is the researchers will be using whatever is current.
