N2 - Three-dimensional large scale incompressible flow simulation was conducted by Building-Cube Method (BCM) that is based on equally-spaced Cartesian mesh method. To exploit expected near-future high performance computer with massive number of processors, simple algorithms have been implemented in the BCM for mesh generation and flow solver. In this study, the capability of BCM for large-scale computation was demonstrated by solving formula 1 car model with around 200 million cells. The computation was conducted on Vector-Parallel Supercomputer system of NEC SX-9 at Cyberscience center of Tohoku University. The parallel efficiency of BCM with flat MPI and hybrid MPI on vector-parallel type system was also investigated.
