Abstract

A casting CAE system named ADSTEFAN has been developed through an industry-university cooperative project in Japan. It is specifically designed for casting engineers to realize ease of use. A couple of days are enough to learn how to use it even if the casting engineer may have little knowledge and experience with numerical simulation. Only a few operations are necessary to prepare input data for solidification and mold filling simulation. Quick calculation with less memory is one of the main features of ADSTEFAN. A huge scale simulation, such as over 100,000,000 meshes, can be solved on an engineering workstation or PC. The various modules to estimate cyclic steady state, size and shape of shrinkage defects and flow pattern in shot sleeve are incorporated into the system in addition to fundamental solidification and filling simulation. Some typical results of application to die casting process are also described.
