This grid makes grid generation easy and reduces generation time cycle when handling complex body geometry such as complete aircraft configuration. These are the main advantages over body-fitted schemes. However, in a simple Cartesian grid generation, when the body dimension is less than cell size (thin body), the separate fluid regions in the cell are mistakenly considered as one fluid region (multiple-flow-region problem), which produces erroneous result. In this paper a new cell cutting procedure is proposed, in which the cell is automatically split into separate sub-cells. In sharp edge of body similar treatment is also performed to eliminate truncation of the edge in a simple cell cutting procedure. The results show that the cell splitting algorithm proposed here is effective in preventing the errors while keeping the number of cells reasonably low.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
