The input datas to modify mooring damping

[wufangyun92]

If I want to investigate mooring damping, which input data should be modified? Because I modified the bottom damping in Moordyn but the FairTen didn't change.

Dear @wufangyun92,

MoorDyn has several sources of damping including seabed friction, structural damping of the mooring lines, and viscous drag.

I presume you are referring to the structural damping, which you can change through MoorDyn input parameter BA or - zeta. See the online MoorDyn documentation for more information: https://moordyn.readthedocs.io/en/latest/inputs.html#the-v2-input-file.

Best regards,
