Injection molded parts with three-dimensional complex geometry, like thick or nonuniform thickness configurations, are widely used today, which boosts the need for 3D simulation replacing the 2.5D model. However, finite element methods of 3D simulation present numerical spurious oscillations, which

This paper presents a finite element solution algorithm for three-dimensional isothermal turbulent flows for mold-filling applications. The problems of interest present unusual challenges for both the physical modelling and the solution algorithm. High-Reynolds number transient turbulent flows with

## Abstract An Iterative Boundary Pressure Reflection (IBPR) method has been developed to improve the accuracy of the flow front generation and transient mold filling simulation in injection molding. The method iteratively calculates the virtual pressure reflection, either positive or negative, at
