Abstract

Present incompressible Navier-Stokes flow solver is developed in the framework of Building-Cube Method (BCM) which is based on a block-structured, high-density Cartesian mesh method. In this study, flow simulation around a formula-1 car which consists of 200 million cells was conducted by vector-parallel supercomputer NEC SX-9. For exploiting the performance of SX-9, the present flow solver was highly optimized for vector and parallel computation. In this paper, the computational result from the large scale simulation and the parallel efficiency in using flat-MPI or hybrid-MPI are discussed.
