温度场数值模拟是铸造过程仿真技术的重要方面之一。有限差分方法是凝固过程温度场解析的常用数值计算方法。基于温度场分析结果的铸件缩孔缩松预测可以优化铸造工艺设计。商品化软件的开发，除依赖有效的分析计算，也依赖良好的界面和前后处理功能。随着计算机技术的发展，微机在温度场数值模拟中的应用获得了迅速的发展
Numerical simulation of temperature field is one of the important aspects of casting process simulation technology. The finite difference method is a commonly used method for numerical calculation of temperature field in solidification process. Casting shrinkage prediction based on temperature field analysis results can optimize casting process design. Commercial software development, in addition to rely on effective analysis and calculation, but also rely on a good interface and pre-and-post processing capabilities. With the development of computer technology, the application of microcomputer in numerical simulation of temperature field has been rapidly developed
