The project aim is the development of common CFD codes that can be shared among researchers and code developers. The basic concept of the code design, the parallel computational method, the multi-block method and its programming were shown in the presentation. As a result of conceptual studies, the following design concept and approaches were determined. (1) Multi-block methods: multi-block structured grid methods are chosen at the first step of dealing with complex configurations of physical objects; (2) Separation of multi-block multi-processor procedures: Parallel computation and multi-block data control processing are clearly separated from the individual CFD solver modules. (3) Portability: The parallelization based on domain-decomposition using the communication library, MPI (Message Passing Interface), is used to minimize the dependency on the hardware architecture. (4) Structure and capsulation: Clear data and program structure and capsulation of modules are used to make the code sharing easier among CFD researchers and developers. To realize these concepts, there are several key features, one of which is the hierarchical structure of the UPACS code that consists of the lower layer for single block level, the middle layer for multi-block level and the upper layer for main loop level.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
