Non newtonian fluid

Hi Everyone…

My name Chairul…

I simulated non Newtonian fluid, but the result didn’t look like a non Newtonian fluid, I think. It can look from the velocity profile. The velocity profile didn’t look like the velocity profile of Newtonian/non-Newtonian fluid. It suppose to be a fluid flow to a 2D rectangular from the inlet to the outlet. But, the result didn’t come with that.
There are something wrong with the dynamic, maybe. I can’t figure it out. Can anyone help me? Because I have a thesis to do, and it’s about simulation of non-Newtonian fluid in porous media.

Thank you for the attention. And I ask for apologize for my bad English.
