We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello Mike,
I am validating the results with respect to one benchmark paper, which has given some stiffness values, the problem I am facing is that, which value i need to adopt for the stiffness connection and fender connction,  a picture related to the details provide in the paper is attached,

, 

I have highlighted the stiffness values, in that i have taken the PTO stiffness value for fender and stiffness upper/ lower end stop spring value used for the x-x, y-y in connection stiffness matrix, i am not sure wheather i have applied them correctly, and im not getting what values, need to be used for RX,RY,RZ in stiffness connection which i need to provide in N.m/degree. and regarding to fender option there is option for friction coefficient, damping coefficient, and stiffness coefficient, reffering to the aboce details, what value i need to adopt for them. 

Please guide me with this.
