In 1962, Denmark's forsund first used computer to simulate the solidification process of castings. Since then, the United States, Britain, Germany, Japan, France and other countries have carried out research in this field. Since the end of 1970s, Dalian University of technology and Shenyang Foundry Research Institute took the lead in the research of this technology in China, and published research reports in 1980 respectively (Guo Keren et al., digital analogy of solidification process of large castings, Journal of Dalian Institute of technology, 1980 (2) 1-16; Shenyang Foundry Research Institute, electronic computer analogy of solidification heat field of castings, foundry, 1980 (1) 14-22. Since then, a large amount of manpower has been invested in the research.
