A software package DFDM/3DFLOW, which can simulate melt flow and heat transfer during mold filling of castings, has been developed. The numerical technique is based on the direct-finite-difference-method (DFDM). Simulated results of the bench mark test is presented. Simulated mold filling patterns and cooling curves of the seven points where thermocouples were located are given. It predicted the air entrapment in sprue and runner and all small melt temperature decrease during mold filling (less than 4K). Calculated filling time was 2.3 s, and solidification didn`t occur during mold filling.
