You are requested to check the mesh sensitivity, time-time stepping and boundary conditions used.

Rahul Jain

Thank you for your kind reply. I have tried different mesh size but with no result. I have attached mesh size and convergence picture here.

I have also tried for running simulation first for constant viscosity for initial iteration and then switch to UDF.

Any suggestion and help will be appreciated
