Dansys is on a distinguished road
Hello every one

i am getting divergent error in ansys polyflow while trying to simulate white metzner model.

i have used polydata to fit the material properties. i have used three data tables viz. 1.viscosity vs. shear rate...2. frequency vs storage modulus....3. frequency vs loss modulus..
power law for viscosity is selected since i need variable viscosity values

my geometry is 2D axis symmetric.
boundary conditions used:::
1. inflow and outflow (volume flow rate) in the inlet and outlet
2. normal velocity and tangential force zero at the wall.(that means slip condition assumed)

i have used evolution scheme in relaxation time [ f(S)=S ].

but in getting divergent error in between the solution updating process.
view listing shows that divergent has occurred..
i have tried many times but getting different different errors related to divergent..\

please help me a little bit.
