Accelerated free-surface flow simulations with interactively moving bodies

One of the challenges of simulating free-surface flow around moored or floating objects is the modelling, including the algorithmic coupling, of objects whose dy- namics is determined by a two-way interaction with the incoming waves. The ’traditional’ way of numerically coupling the flow dynamics with the dynamics of a floating object be- comes unstable (or requires severe underrelaxation) when the added mass is larger than the mass of the object. To deal with this two-way interaction, a more simultaneous type of numerical coupling is being developed. The quasi-simultaneous method will be demon- strated on a number of simulation results for engineering applications from the offshore industry: the motion of a moored TLP platform in extreme waves, and the launch of a free-fall life boat.
