Hi!
I'm working on a project that involves analyzing the response of a lightweight surface buoy that is moored to the seabed. The water depth is about 10m. The issue is that the program does not accept the mass/unit length of the mooring cable I wish to input.
I get an error that the value should should be more than 0,13781 kg/m. However, the cables I want to analyze are much lighter than this and some of them are positively buoyant. I have been trying to find more about this on the manuals and online forums but I can't.

Never mind, I got the solution after talking to someone at ANSYS. Turns out the equivalent cross-section is just used as a dial to regulate the buoyancy and doesn't have any physical significance. So a higher mass/unit length can be used with a corresponding equivalent cross-sectional area keeping the density of the cable same.
