AxCd PropD, HydroDyn

Dear all, I’d like to know if there is a correction for the kinematics over, e.g. a large heave plate for the quadratic Morison drag caclulation. Is the the joint velocity (at heave plate center) taken to be the one for the heave plate drag calculation or is the velocity dependent on the location over the heave plate (for example if the OC4 platform pitches, the velocity at the outer points of the heave plates is larger). I checked the source code but coulnd’t find anything. Thanks in advance!

Dear Frank,

HydroDyn only calculates the wave kinematics at the center of the circle when calculating the hydrodynamic end loads at joints.

Best regards,

Thank you, Jason!
