抄録

In CAE analysis of casting phenomena such as mold filling and solidification, the finite difference method is often adopted when building the difference equations. However, this generally results in poor shape approximation accuracy since meshes created for highly curved and complex casting surfaces have to include step formations at end sections. Consequently, this causes predictions for mold filling and other phenomena to diverge from actual results, and is one reason why analysis accuracy is not sufficient to provide general solutions. To resolve this issue, an analysis technique was developed using the porous media method. This method enables highly accurate analysis within a practical calculation timeframe by improving shape approximation accuracy without reducing mesh pitch.
