ABSTRACT --- Finite Element Method (FEM) simulation of 3-D flow and temperature evolution
during extrusion cycles is being integrated at production sites in extrusion tool conception and
fabrication. The model has been validated and calibrated by comparison with measurements of
pressure and temperature in various process conditions. The development of specific methods and
algorithms have permitted a reduction in both the geometry preparation time (FEM mesh), and the
CPU time so that the schedules imposed by production can be obeyed.
