本文综合性地论述了铸件凝固过程中计算机数值模拟技术的历史、现状及发展趋势。同时详细地介绍了铸件疑固过程数值模似中各种数值计算法．并比较了它们的应用诗点、本文还指出铸件凝固数值模拟是铸造工艺ＣＡＤ的基础．后者是前者向实用化和商品化发展的必经之路。
This article comprehensively discusses the history, current situation and development trend of computer numerical simulation technology in solidification of castings. At the same time, the various numerical methods in the numerical simulation of the process of suspicious solidification are introduced in detail. And compared their application poetry, this paper also pointed out that casting solidification numerical simulation is the basis of casting process CAD. The latter is the only way for the former to be practical and commercialized.
