Hello,

I started recently using Ansys Aqwa (Hydrodynamic diffraction), my goal is to realize a numerical simulation about a buoy which is linked (very small gap) to a fixed tower. The results I get show that the Buoy tilts up and down in the model if it were a ship. However, in reality the buoy only act with the heave of the wave in a completely vertical movement. Also, it seems that the structure interaction between the buoy and fixed tower, physically absent.
What is the possible config to give the buoy only a vertical movement ?

Best regards.
