Base on analysis of 3D body flow model,that mid plane and skin mesh based technique for CAE of gas assisted injection molding(GAIM)is studied.It is pointed out that 2 5D Generalized Hele Shaw model is an applicable technique for 3D body flow simulation of GAIM,because it is of good flexibility and astringency,and can speed up the simulation.It is also concluded that,in order to obtain high accuracy of CAE of GAIM,shell and beam cells yielded from such a technique are of great importance for the pretreatment.
