<p>So if I understand correctly, I need to have a total 37 connection stiffness matrices for the joints and two fixed “equilibrium” connection stiffness matrices for the mooring lines right? I have made an image which shows all the connection matrices I need to define in my simulation as highlighted in yellow. Could you please let me know if this is correct?<\/p><p><\/p><p>Also I have some questions on your next comment:<\/p><\/p>\n

  1. You mentioned – “Note that the diagonal 6×6 submatrices may be the assembles of sub-matrices from all the linkages” … I could not quite understand this. Because the reference article I am referring to gives the matrices as shown in the figure below. So should I give all the 37 connection stiffness matrix (excluding the mooring lines) as a diagonal matrix with C11,C22,…C66?<\/li>\n<\/ol>\n

    <p><\/p><p>2. If I use the beta options and include the connection stiffness matrices for the hydrodynamic response analysis, do I still need to define joints such as hinge joints or ball or socket? And do I have enable a linear cable connection for the mooring lines? <\/p><p>Please help me out with this as I have been trying a lot of things which have not been working.<\/p><\/p>\n","protected":false},"template":"","class_list":["post-392114","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
