Now newtonian convergence
Hi, Im simulating a steady flow in a tube. As its a 'wellbehaved' flow, i used extruded 2d simulation. For the newtonian fluid I got great results. But for the nonnewtonian fluid it either doesnt converge or the results arent physically correct. How can can I get a good result? I've tried chganging the mesh, altering the inlet velocity, using other turbulence models and nothing worked. Thanks

Dear Gustavo,
What "nonnewtonian model" are you using? Opaque 
Re: Now newtonian convergence
Visc=k*y^(n1), and I also bound the equation with a min and a max, just like in the tutorial.

Re: Now newtonian convergence
Dear Gustavo,
I assume that "y" mean shear strain rate, and not "y coordinate".. Correct? Opaque..

Yes...
