The level of numerical simulation has reached a high level in developed countries, especially in the United States and Europe since the 1960s. With their strong economic foundation and technical strength, they have made remarkable achievements in this field. In China, although it started late, its development speed is very rapid.
The computer simulation technology of casting solidification is a frontier subject in the development of casting industry. Its development process can be divided into the following three stages:
- The first stage, the basic research stage, focuses on the calculation and Simulation of temperature field;
- The second stage, in-depth research stage, is mainly the simulation of temperature field, prediction of defects and flow field, and the simulation of microstructure;
- In the third stage, the in-depth research continued, the temperature field and flow field developed in a deeper and wider direction, and the microstructure simulation was carried out in an all-round way and became the mainstream.
