There is a need to convert ship geometry available in STL mesh format (as shown below) to a NURBS surface for Computational Fluid Dynamics study. The manual way of doing it is to create station curves by joining points and then create surfaces. It’s quite complicated for the bulbous bow, bow flare and the propeller housing sections. The mesh2nurbs function creates a very coarse surface, not acceptable for CFD analysis. The hull should be smooth and watertight.
Converting the hull form needs to be done in a very short time, and an automated script would be very useful.
Does anyone have any experience with similar problems. Any suggestion would be helpful.
