Hi, from 2022R2, Aqwa-Rigid Dynamics-AeroDyn co-simulation system for floating wind turbines is available. This workflow needs Ansys Twin Builder and Ansys Mechanical. More details about it can be found in Aqwa User's Manual Section 8.3.  

Regarding external force, you can find a python example in the installation folder under aqwa/utils/ExternalForceCalculation while the FORTRAN and C examples can be found under aqwa/doc. If Fortran or C language is used, then compile your own routine and then put the *.dll file (Windows) into the same directory as the Aqwa executables. More information can be found in Aqwa Reference Manual Chapter 30.

Hope this helps.
