Abstract: Casting industry is critical to the national economy.
However there exists big gap between the casting technologies at home
and abroad. One of the important future trends is the application of
numerical simulation technique to substitute the traditional empirical
research methods. Numerical simulation has become the necessary way to
up-grade the traditional casting industries and been paid with much more
attention. With the mature of macro-modeling of casting process,
micro-modeling and multi-scale modeling become one of the hottest
research frontiers attracting many researchers and engineers. The
current research hotspots and the development trends of modeling of
casting processes are mainly introduced, especially on the mold filling
and solidification processes of net shape casting, the stress and strain
analyses, the prediction of the formation and evolution of
microstructure and the multi-scale modeling under concurrent engineering
environment. At the same time, the related achievements in our country
are given with special emphasis.
