with the development of computer technology, foundry CAE technology has made rapid progress. Commercialsoftware packages of casting process simulation, therefore, have become more and more practical. This paper introducesboth the recent developments and some applications of InteCAST software, a commercial numerical simulation softwarepackage for foundry industry, with more than 120 customers all over the world. The function modules of lnteCAST8.0 andsome new techniques, such as uneven mesh technology for mold filling simulation and numerical mouse technology fordata visualization, were introduced. Several applications on special castings such as investment casting, low pressure diecasting, and high pressure die casting, were given. These applications showed that the software can help engineers tooptimize casting process by forecasting casting defect. with the development of computer technology, foundry CAE technology has made rapid progress.
