This volume is dedicated to simulation of the Aluminum Extrusion Process and the model that has been developed to predict the performance of a complex extrusion die accurately, within time spans that can definitely compete with the time necessary to perform a trial-pressing.

Based on the comparison of various numerical experiments it is concluded that it is important to incorporate the temperature dependence of the viscosity, as well as the shape of the outflow surface, and occasionally the deflection of the die.
Comparison with industrially obtained experimental data shows that the model predicts the flow field and the resulting profile shape accurately, even for very complex profiles.
