How to simulate Die Swell in Inspire Extrude Polymer

María Luisa de la Cruz Martínez

Hello,

I have simulated the flow of HDPE in a die head and I want to see the effect of die swell at the exit of the die.

I also wanted to see the decrease of diameter caused by the haul off. Right now I have added a boundary condition using puller but I only see the result in z direction with no decrease of the diameter.

Thank you and best regards

1) First try die swell effect in Inspire Extrude. Please refer to attached InspireExtrude_Polymer_Die Swell.pdf for brief notes on die swell test model.

2) For puller effect, currently this has to done by manual editing of solver deck or using legacy interface - HyperMesh/HyperXtrude.
