  The two dimensional mold filling simulation technique proposed in the previous paper has been extended to a three dimensional one. In this technique, which is based on the Direct Finite Difference Method, since the hexahedral elements can be employed, the original shape of a casting can be preserved in its simulation model. The momentum equation is applied in each outer nodal region while the mass conservation equation in the inner nodal element which is the same as the element. Although two dimensionless parameters, <i>βv</i> and <i>βs</i>, are defined to predict the movement of free surface more accurately, a more simple technique for the estimation of <i>βs</i> was used in the three dimensional case. Some numerical mold filling examples showed efficiency and promising results of the proposed technique.
