ABSTRACT --- The paper presents 3-D Finite Element Method (FEM) system for
simulation of extrusion. It simulates non-isothermal steady-state flow of visco-plastic material
in container and die outlet. The developed code provides completely automated mesh
generation, effective simulation of material flow and output of information on material flow,
temperature distribution, and some integral characteristics like profile bending and profile
twisting which are necessary for prediction of product quality. The developed software was
applied to simulation and optimization of different extrusion processes, including profiles
having opened and closed shapes. The FEM system supports the interface with solid and
surface CAD systems through STEP and IGES format. The code is supposed to be an
effective tool for extrusion technology development in the industry, due to its userfriendliness
and use of PC.
