Need advice on how to perform plastic deformation of a metal through a die in extrusion

The assembly folder does not contain part files.

This is not a type of simulation that can be done with SWX Sim or flow.The element distortions would be too large. You would in solution remeshing or an Euler code, assuming the die does reduce the cross section in the order of a percentage or more. This is a pretty sophisticated simulation.

I confirm what Bill says, this is not something you can do with SOLIDWORKS SImulation.

One of our customer uses a solution developed by French Univeristy.
