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. |
