Abstract : A grid generation procedure has been developed to create complex block grid systems, beginning with the generation of block surfaces, up to the generation of the full block volume grids. Parallel to this, a multiple block Euler equation solver has been developed using a hybrid flux vector split and split MacCormack scheme, written to allow very general boundary conditions specification. The two codes are utilized herein to generate an inviscid analysis of an entire F-16 transonic flowfield. Preliminary results are presented and are seen to compare well with experimental data. Even better correlation with experimental data is expected once a fully converged solution is obtained.
