ANSYS 17.2 License not Available for Coupled Solver

Hey everyone,

I'm attempting to run a coupled fluid-structure analysis with ANSYS Workbench 17.2. I have licenses individually for Fluent and Mechanical, but even though the Fluent and Transient Structural runs work fine on their own, when coupled using the process described here (Part 1: ; Part 2: they error out as shown:

 System coupling run completed with errors.

Attached is an image of the runtime errors we get during the co-simulation process. 

It seems that there's an additional coupled-simulation license required for this type of co-simulation? If so, does anyone know how we can obtain this license?

Thanks a lot
