Dear all,
I had extracted the mooring stiffness matrix from MAP++ using pymap, I have some doubts in it.
[1] I want to know whether there is any relation exist between the elements of stiffness matrix or not?
[2] Is there some existing theoretical form of stiffness matrix just like the mass matrix?
Best regards,

Dear @Kajal.Thakur,
I’m not sure what kind of “relationships” you have in mind, but the mooring stiffness stiffness matrix depends on the line types (catenary, taut, or semi-taut) and geometry of the mooring lines and their interconnections.
Best regards,
Dear @Jason.Jonkman ,
Actually when I am changing any line property such as EA etc. the whole mooring stiffness matrix changes. I want to check how the values are changing as I am not able to identify any particular pattern between the former and later matrices.

Dear @Kajal.Thakur,
That is likely because the mooring system stiffness depends not only on the elastic (EA) stiffness, but also the geometric stiffness associated with the line type and line geometry.
Best regards,
