Abstract
Finite element methods offer the potential to greatly refine mold filling analysis. As a consequence, there is strong pressure to apply this technology on a routine basis in industry. Unfortunately, traditional finite element techniques are not adequate to design a viable model of the flow of molten plastic into a mold. This paper explains the mathematical problems that must be solved. It describes why the widely used classical matrix techniques give erratic results, and demonstrates that it is mandatory to apply a total dynamic analysis to obtain a reliable mold filling simulation. A new technique is introduced to solve the problems caused by non-linear material properties and moving boundaries.
