【Abstract】 Discussion on the 3 D numerical simulation of complex shaped casting solidifition process with FEM was carried out in this paper, concerning how to establish 3 D control equation of FEM using tetrahedron element in casting mould and casting. For revealing heat transfer at casting interface,using pentahedron element link the elements of casting and casting mould.更多还原
