Abstract: A computational model on the melt flow simulation in the casting process includes the continuous equation and partial differential equations of the momentum equation. The momentum equation is divided into two parts by the fractional step method.The method of characteristics is used to solve the first equation. The second equation combined with the continuous equation is changed into the possion equation about pressure. The equation is solved by the iterative method, and the convergence and the stabilization conditions of the equation is analyszed.

Key words: method of characteristics, convergence, iterative , fractional step method
