It is usual to define a configuration by using a CAD (Computer Aided Design) tool. It is necessary to construct a grid system around it for analyzing the flow field. But this part is a bottleneck since the usual general-purpose CAD software packages do not support the generation of surface grids suitable for CFD analysis. In this paper, the preliminary work of surface gird generation based on the CAD data is reported. Conversion format from a CAD tool is the IGES (Initial Graphic Exchange Specification) format. The configuration from the section data is first reconstructed so that the isoparametric curves are quite suitable as the grid curves. Then a surface grid is generated by assigning the number of grid points needed.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
