Numeca is happy to annonce that Fine/Marine, the leading CFD solution for naval architects, has been used succesfully to check the static and dynamic properties of the boat called "TYDe 68"designed by Mr. Tanton Y-M, naval architect and owner of Tanton Yachts.
Thanks to its unique features (adaptive grid refinement, quasi-static approach, sub-cycling method etc.) Fine/ Marine has been used to predict accurately the TYDe 68 wake patterns at different speeds, including free trim and sink. In a second step,these results (pressure distribution, free-surface elevation, streamlines, etc.) allowed optimization of the hull shape by reducing total drag, reducing fuel consumption and emissions at cruise speed.
" CFD computations for marine applications are nowadays routine work for naval architects at each steps of the design process", comments Yves-Marie de Tanton. "A coarse mesh, can be for instance used at the very beginning of the design in order to bypass the empirical relations and obtain a first idea of the boat behavior. CFD can also be used at a more advanced stage of the design process by adapting the mesh and replacing the classical panel method. Eventually, a detailed mesh will provide accurate results (< 1.5% error) for classical resistance computations which are of major interest to all naval architects". Yves-Marie de Tanton states.
