K. NAKAHASHI, S. TAKAHASHI, T. ISHIDA

Abstract


Currently CFD has become an indispensable tool for analyzing and designing aircrafts. Wind tunnel testing, however, is still the central player for aircraft developments and CFD plays a subordinate part. In this article, demands for nextgeneration CFD are described with an expectation of near future PetaFlops computers. Then, a Cartesian mesh approach, as a promising candidate for next-generation CFD, is discussed by comparing it with the current unstructured mesh CFD. It is concluded that the simplicity of Cartesian mesh CFD from the mesh generation to the post processing will be a big advantage in the days of PetaFlops computers.
