This paper presents a method for evaluating the flow about an arbitrary three-dimensional body using the submerged patches of triangular elements with quadratic variation of source strength.

Three-dimensional body-fitted grids perpendicular to the boundary are generated in this paper by applying equilibrium relation of forces acting on the ideal non-uniform linear elastic lines.

While skin is fairly two-dimensional and can easily be placed on a body, three-dimensional organs present a different challenge.
