A mold filling simulation method for die casting is proposed. New type cell named FS Cell is employed to improve the accuracy of mold filling simulation by Simplified Marker And Cell (SMAC) method. The FS cell has a free surface paralleled to two dimensional (X-Y) plane.
Exsistence of the free surface is considered by fluid filling ratio of the mesh used by SMAC Method.
Pressure is assumed to be constant in the FS cell and the fluid filling ratio is determined to satisfy mass conservation equation after determining the velocity of the FS cell by momentum equations.
Availability of quasi three dimensional model to die casting problem is examined and some applications of the extended SMAC method are described.
