Hello, 

I am trying to simulate the motion of a floating body due to wind forces and am doing a 2D simulation on it. I have found it difficult to simulate floating motion in fluent using 6 dof and am searching for alternative options. I am thinking that it might be easier to export the aerodynamic load on the body to AQWA and simulate the hydrodynamic motion there. Is this a viable option? Is exporting forces to AQWA possible?

It seems that it is not a suitable option. The aerodynamic load is the function of the motion of the structure, i.e. it depends on the position and orientation of the structure. But you think the aerodynamic forces have no relation with the actual locations of the structure in a time domain analysis, it can be imported into the Hydrodynamic Response time domain analysis, see Aqwa User's manual
