    The redundancy that occurs when vortex-lattice methods are applied to closed bodies is discussed. The solution to the no-penetration condition in terms of the circulations around the closed loops encircling the elements of the lattice is not unique, but the circulations around the individual vortex segments of the lattice are. Two procedures to solve the no-penetration condition are explained and illustrated by means of a simple example in which the flow over a sphere is modeled with a very crude mesh. Then the mesh is refined, and it is shown that the procedure produces an accurate approximation to the exact solution. (AIAA)
