### 13.1.7. Product Licensing Considerations when using System Coupling

The licenses needed for System Coupling analyses are listed in Table 13.2: Licenses required for CFX as part of a System Coupling analysis. No additional licenses are required for the System Coupling infrastructure.

The simultaneous execution of coupling participants currently precludes the use of the license sharing feature that exists for some product licenses. The following specific requirements consequently exist:

- Unless you use a Mech CFD license, distinct licenses are required for each coupling participant. One Mech CFD license permits multiple coupled solvers.

- Licensing preferences should be set to “Use a separate license for each application” rather than “Share a single license between applications when possible.”

The requirements listed above are particularly relevant for ANSYS Academic products.
