Coupling between Hydrodynamics and aerodynamics

Dear Sir,
I’m planning to implement the concept mentioned in the picture. So, to explain, I want to get tower base load data at every time step and input my position, velocity, and acceleration terms in FAST. So, where should I make changes? Please suggest.
Thank you.

Dear @Navneet.Kumar,

A similar question was discussed in the following discussion on the OpenFAST github site: FeaCoupling of an External floater (platform+mooring) with Openfast #791 · OpenFAST/openfast · Discussion #801 · GitHub. To summarize, the coupling you propose is not possible without major changes to the ElastoDyn source code. This is because equations of motion of ElastoDyn are written assuming the six-DOF motion of the platform is solved by ElastoDyn. The coupling you propose would require restructuring of the equations of motion in ElastoDyn to accept motion instead of load input.

Best regards,
