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 next-generation CFD are described with an expectation of near future PetaFlops computers. Then, Cartesian grid approach, as a promising candidate for next-generation CFD, is discussed by comparing it with the current unstructured grid CFD. It is concluded that the simplicity of the algorithms from grid generation to post processing of Cartesian mesh CFD will be a big advantage in the days of PetaFlops computers.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
