InteCAST casting process simulation system,adopts state of the art numerical simulation technologies of mold filling and solidification process to analyze the casting process. It can be applied to accurately simulating the physical phenomena of solidification, mold filling, coupled fluid flow with heat transfer, and thermal stressduring the casting process. After more than thirty years development by Huazhong University of Science and Technology(HUST) and continuous improvement through applications in foundry enterprises, InteCAST is the most famous casting process simulation software in China. There are more than 2700 licenses used in about 800 foundries and 50 universities of China, and also 15 licenses used in USA,England, Switzerland, Singapore, Malaysia and Indonesia.
