mixing of viscoelastic fluid
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.
