How to put friction in non newtonian fluid?

Please login with a confirmed email address before reporting spam

Hellow, I really wonder the method to use friction function in 3D.
But i couldn't find it... already i did the simulation of friction in 2D.
even if the modelings of 2D and 3D are same, results are different.
I really don't understand that... Why....
So i tried to set the wall was slip and give the equation of friction both 2D and 3D of modeling.
But only 3D has something wrong. Because the result of 3D was same with only slip state.
it doesn't make sense...

If you guys know some ways, let me know. and if you wonder the results of them, leave some
reply.

I really need your help.
