HyperXtrude

Conjugate Heat TransferExtrusion of Aluminum Coupled with Heat Transfer Between Tool and Part

This example demonstrates the capability of HyperXtrude to model heat transfer between the deforming material and stationary tool. During extrusion the mechanical energy is converted into thermal energy. One of the factors that influence material deformation is the energy transfer between the tooling and deforming material. Accurate modeling of material flow and heat transfer requires modeling of heat transfer between the tool and deforming part.

Results from extrusion of axisymmetric circular aluminum rod are presented here. The results from initial mesh run indicate large solution error in the region upstream of the die entrance. The adapted mesh results show the error in these regions is reduced. Also, the adaptation module, in addition to refining the elements near the die entrance, has enriched the elements from linear to quadratic.
