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,

Fenders (as well as Cables, Tethers and Joints) are not considered in a Hydrodynamic Diffraction analysis, but you can introduce a relative motion constraint into the Hydrodynamic Diffraction calculation using Connection Stiffness matrices. Please see the last reply from me in this thread: Implement of constraints between two objects in frequency-domain calculations (ansys.com)

Let me know if you have any problems setting the Connection Stiffnesses up.
