Dear all of u
I am looking for 3D BEM code for calculating wave pattern and wave resistance of underwater moving object. Is any free code available on line?
Thanks

3D BEM, as in Blade Element Momentum theory for rotors?

Do you have the 3D codes about Blade Element Momentum theory for rotors?

No such thing. I thought that's what the OP was asking for and I was going to point out the error in that line of thought. Blade Element Momentum theory is a quasi-2D theory, expanding beyond that invalidates the assumptions inherent to its formulation.

It is possible to couple BEM with CFD and treat the rotor like a momentum source with its output determined by BEM and inflow conditions driven by the CFD model.
