OpenFOAM is one of two CFD packages that are under consideration at ST for our internal CFD research and ultimately FSI solutions.
In the last months OpenFOAM has been implemented for both stationary and 2-6 DOF cases, generally involving free surface interaction. This implementation is part of ST’s ongoing commitment to be a simulation based practice employing the latest technologies for improved performance.
Here is one example showing a candidate catamaran hull tested at 15 knots. Data such as resistance and moments to maintain proper trim are compared between a number of candidates. With a simulation like this one, the effect of the transom immersion can be more accurately understood.
