Ethan Thompson That's the answer I got through the Portal. Basically, this is currently not an available feature within Discovery. Using the FLuent license in Refine mode is only allowed for fluids and thermal, and not for pure conduction. Pure conduction is a much simpler solution than fluid with heat transfer and it should have been allowed if a customer has the Fluent license. I was told through a direct email by a senior technical ANSYS personnel that this feature will be included in a future version of Discover (possibly by the end of this month). Thanks, Kamel.
