Reply To: AQWA: Hydrodynamic response error

Extreme larger wave height of 1m (comparing to the draft of 0.1m) and short wave length of 26m (comparing to the model size of 15m) will have relative large motions related to the mesh size.

(1) HR time domain analysis is nonlinear analysis, but HR frequency domain statastic analysis is linear which does not check the relative motion criterions.

(2) Wave direction is 180 degrees, Roll and Yaw motions should be very small (or zero) if the system is port-starboard symmetry.

(3) It is a hydrodynamic interaction structure model, the hydrodynamic damping coupling terms may be big.
