Hello Mr Raban.  Thanks for your reply.  The link you provided suggested separating the Teaching and Research license data and running them on two separate license servers.  Then the user would need to somehow select which license server to use before starting the Ansys software.   That may work but seems overly complicated compared to using the anslic_admin program.

Both the Teaching and Research licenses seem to be functionally identical.  They both have the same feature name.  The only difference is a "tp:a" (for research) and "tp:at" (for teaching) in the VENDOR_STRING part of the FEATURE/INCREMENT line in the license data file. 

Since there is no functional difference between the Teaching & Research licenses, maybe it is no longer necessary for users to choose between them.
