Abstract : Numerical solution of the partial differential equations for the generation of surface grids requires a specification of the forcing function which depends on the geometry of the given surface. The data for the surface is usually in discrete form. Methods have been developed which fit a function over the given data. For complicated shapes, e.g., an airplane, the functional fit and the eventual grid generation for the fuselage and wings are done separately and then integrated later. Keywords: Grid generation; Curvilinear coordinates; Numerical methods; Computational fluid dynamics.
