Hi,

I checked the above two points you mentioned in the reference article and it seems they are not specified the reference DoF for the stiffness matrix. All they have provided is this matrix. Also this is link to the reference article: https://www.mdpi.com/1996-1073/17/9/2059

 

But one question that is very weird is when I dont specify any connection stiffness matrix and I run the diffraction analysis just with the mass and inertial properties of the 15 bodies, the RAOs are still lower than the reference values. So does this mean that the mass and inertial properties are wrong??
