Abstract

Abstract

Main functions of a multi-medium problem pre-processor PreGenGrid was introduced. Including description of complex geometric regions, mesh generation of block area, data structure of the grid management, the seamless splicing technology of block meshes. Automatic mesh generation/automation patching of PreGenGrid was presented with emphases. Mesh examples were also provided. PreGenGrid is an ideal tool for computer aided in simulations of the multi-medium problem analysis in scientific computing.
