| Abstract: | Based on the module for solid modeling in AutoCAD R12, the data formats of six basic geometric bodies in DXF file are analyzed. A program for the 3-D mesh subdivision for finite difference calculation of a solid casting has been developed. An example of solid modellhg and mesh subdivision for a practical casting is given. The program can be used in the preprocessing of three-dimensional numerical simulation of heat transfer and fluid flow of molten metal during the formation of a casting. |
