Hello,

I am trying to simulate of mixing process of a viscoelastic fluid in a twin screw mixer using Polyflow. In order to solve the problem I want to use differential viscoelastic flow as fluid model.

Also I wanted to use mesh superposition to simplify the mesh generation of the flow domain but I figured out that mesh superposition method can be used only for a generalized Newtonian problem which does not work for my fluid. I wanted to ask you if there is any way to simulate the mixing process of a viscoelastic fluid using Polyflow. 

I have searched from the user`s guide and the tutorials but unfortunately I have not made any results. I hope you can answer me and explain it to me. 

Thank you for any help you can offer.

Hello

Is there a particular reason why you'd want to use mesh superposition in Ployflow? 

I am not sure if you have watched this 3-part video tutorial for modeling blow molding on Youtube. Although it does not cover many aspects that you requested in this post, it might be of some help to you.

Thank you.

Best Regards,

Karthik
