Hi Mike,
I am running both Hydrodynamic Diffraction and Hydrodynamic Response simulation,

This is the arrangement of fenders that I have used for the spar and torus in time response analysis, and which type of fender do I need to use, to keep the relative motion between both the structures only in heave direction, 

like I have used the fender as the floating kept the action in Z direction, or do i need to change it.

These are the values that I have used for fenders, 50000N/m for stiffness coefficient, and 0.3 for friction coefficient, I didn’t got what value need to be taken for damping coefficient, according to your last message do I need to adopt ‘Stiffness upper/lower end stop spring’ for the stiffness coefficient.
