Hello everyone, I am having some problem with my model. While simulating this model in Fluent I used outflow for my outlet. Can anyone please tell me what boundary condition can replace outflow in star CCM+.

Thank you very much Kasey. Do i need to change the turbulent intensity ratio (TIR) or voscosity ratio (TVR), because at the inlet TIR = 1 and TVR = 10.

Thank you very much everyone. My model is running fine. Now I am trying to create finer mesh at the middle part of my cylinder (throughout) ( shown by the red sign in the figure). Could you please tell me how can I do that. Thanks in advance for your help.
