An efficient grid interfacing zonal algorithm has been developed for computing the transonic flowfield about three-dimensional multicomponent configurations. The algorithm uses the full-potential formulation and the AF2 fully implicit approximate factorization scheme. The flowfield solution is computed using a component-adaptive grid approach in which separate grids are employed for the individual components in the multicomponent configuration, where each component grid is optimized for a particular geometry. The component grids are allowed to overlap, and flowfield information is transmitted from one grid to another through the overlap region. An overlapping grid scheme has been implemented for an isolated wing and a noninteracting wing/pylon/nacelle configuration. Numerical results show that the present algorithm is stable, accurate, and promises to be effective in computing the flowfield about complex configurations.
