Thank you for your attention！
I'm using this software to do some simulations of non-Newtonian.But there some question.
1.Is it necessary to create two liquids to use non-Newtonian fluid model? How to establish a non-Newtonian fluid model?
2.A very important issue is that there is no friction between non-Newtonian fluid and the boundary conditions. How to change the friction between the fluid and the boundary conditions the size.（Very important！）
Looking forward to your reply！
