Please check the critical damping output. I guess that in your model only Strucre#3 and Structure#13 have mooring stiffness in x-direction. The additional dampings are used always in the program, but the critical damping percentage output of a DOF could be zero for a structure if there is no stiffness in that DOF.Â
