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.

Hi Ian,

I want to simulate a floating object that oscillates freely in water. I want to use the z coordinate of the deepest point of the floating object to calculate the hydrostatic pressure acting at that point. Then this hydrostatic pressure will be used to define the maximum coupling pressure in the load curve. 

With the default values of PFAC, I find some numerical oscillations in the solution of the rigid body kinematic quantities. I would like to try using a coupling pressure load curve to see if these oscillations can be minimized.

Thanks & Regards
