Abstract
The conditions of casting with a permeable mold having a cavity and a runner can be optimized by a computer simulation method of (1) dividing the mold and a cavity thereof into a plurality of elements; (2) providing mold properties, a pressure and a velocity of a melt flowing into the runner as initial data with respect to each element; (3) performing computations in a step-wise manner to determine the movement of a free surface of the melt and a rate of gas flowing through the mold until the cavity is filled with the melt; (4) calculating a total volume of voids generated in the melt; (5) examining whether or not the total volume of voids is substantially zero; and (6) if the total volume of voids is not substantially zero, repeating the computations with at least one of the initial data modified until the total volume of voids becomes substantially zero.
