Synopsis: Computer Aided Design of gating system is important part of computer aided casting plan. According to the character of vertical parting mold gating system, using a matrix of flowing process the application software has been developed. The mathematic equation of metal liquid flowing in the system and the boundary condition and the numerical simulation method has been gaven in the paper. The results of the numerical simulation were in good agreement with the results of water model simulation experiment. It is clear that the computer numerical simulation method is good for calculation of flowing process in the vertical parting mold gating system. The software is in common use and available.
