Abstract£º Most injection molded parts are three-dimensional, with complex geometrical configurations and thick£¯thin wall sections£®A 3D simulation model will predict more accurately the filling process than a 2.5D mode1.This paper gives a mathematical model and numeric method based on 3D model£¬in which an equal-order velocity-pressure interpolation method is employed successfully£®The relation between velocity and pressure is obtained from the discretized momentum equations in order to derive the pressure equation£®A 3D control volume scheme is employed to track the flow front£®The validity of the model has been tested through the an analysis of the flow in cavity£®
