Hi Mike,

Could you also explain how to use disc elements to define the viscous roll damping. The vessel which I am analyzing, does not have bilge keel. So, I want to include only the viscous drag component of the total roll damping. Is it something like defining many discs along the hull and give some drag coefficients? How do I transfer the wetted area to these discs? Alternatively, is there a better method to do this?

Thanks.
