At Rolla, sea keeping simulations are routinely performed on fast yachts. The code used solves the Navier-Stokes equations moving in time, and the VOF (Volumes Of Fluid) method is used to model the deformation of the free surface.


Regular or irregular incoming waves with any length and height can be modeled that test extreme movements of the hull.


The results of particular interest are concerned with the added resistance of waves, vertical accelerations onboard (for comfort analysis) and pressure impacts (fundamental for correct hull structure).
