A method for determining the velocity ol a threedimensional fluid flow over a submerged body is provided. A plurality ol finite volume cylindrical elements are used to represent the distribution ol vorticity at the surface geometry ol the body. The vorticity distribution is used to determine the velocity field ol the flow according to the Biot-Savart integral which is solved for in a cylindrical coordinate system.
