【Abstract】 The solution of the boundary conditions is a very pivotal process during the solidification simulated by FEM. In this paper, authors present that how to solve the two important boundary conditions, i.e. convective heat transfer coefficient and heat flow density during solidification of centrifugal casting process , and the disposal of the latent heat in the FEM simulation. Thereby, the precondition of the FEM simulation can be achieved.更多还原
