摘　　要：概述了多介质问题数值模拟前处理程序PreGenGrid的主要功能,着重介绍了该前处理程序网格自动生成功能和多介质问题多块网格生成后的无缝拼接技术,给出了多介质问题网格实例,验证了前处理程序PreGenGrid的特点.PreGenGrid是科学计算和复杂工程技术人员进行数值模拟的理想工具.Main functions of a multi-medium problem pre-processor PreGenGrid was intro- duced, including description of complex geometric regions, mesh generation of block area, da-ta structure of the grid management, the seamless splicing technology of block meshes. Auto-matic mesh generation/automation patching of PreGenGrid was presented with emphases. Mesh examples were also provided. PreGenGvid is an ideal tool for computer aided in simulations of the multi-medium problem analysis in scientific computing.
