Mold-filling of polymer melt in three dimensional thin parts is a viscous incompressible flow with moving boundaries.Based on generalized Hele-Shaw flow theory,the finite element systems for pressure fields are constructed by the Control Volume Methods.The advancing of melt front is traced by a hybrid FEM/Control-Volume method and the dynamic simulation of the mold-filling process is achieved.
