Dear all,

I'm now trying to simulate a ship moving headway in wavy sea conditions using VOF model and Dynamic Mesh with 3DOF (pitch, heave, and forward translation). Are there any possible ways to define the pitch and heave motions (Iyy rotation and z-translation) to be dependent on forces and moments (6DOF on), while the forward translation (x-direction translation) to be independent of forces and moments (6DOF passive)? This is because it seems I can only define the initial forward velocity but I couldn't make it constant while its pitch and heave behaviors can be simulated.
