On the left and right sides are two floating docks, the model is the same, the rear side is a wall, and the wave is incident in the 0° direction, but why the motion response of these two floating docks and the force of the hinge connecting the floating docks are different？Is there any setting to enablemultibody?The additional mass in the frequency domain is the same, but the motion response under the action of regular waves in the time domain analysis is different from the force on the hinge。

Please check if the structure of the rear side wall is fixed by a fixed joint in the time domain analysis.  If the meshes and joints are all symmetric with respect to the central vertical XZ plane between floating docks, the results should be symmetric.
