Abstract :
This paper reports the results of a parallel computation of a transonic flow past a 3D wing using the Hanbit-1 computer, a hypercube parallel computer developed at KAIST (Korea Advanced Institute of Science and Technology). Two different numerical schemes, one a lower-upper symmetric Gauss-Seidel (LU-SGS) method and the other a Runge-Kutta time-stepping scheme, were used. The performance of the Hanbit-1 was assessed based on the present parallel computation with domain decomposition
