The purpose of the study is to investigate practical advantages, a potential for low computer time and fast convergence as well as accuracy to a steady state solution, of a lower upper symmetric Gauss-Seidel implicit relaxation method using overset grid technique and develop an efficient parallel computational algorithm with a data structure by one dimensional array. This method is applied to viscous turbulent flows around multi element airfoils. Almost linear performance of the speedup ratio in parallel computing is attained up to 16PEs on the Hitachi SR2201 computer. Comparison of the numerical result with available experimental data shows good agreement.
