I am doing a turbulent flow simulation (Re = 10000). I am using different mesh to see the results. Each time i am using a mesh, i am getting different results. How to know that which results is right. Is there any criteria/number which tells you that you are doing with the correct mesh. Thanks.

What type of simulation are you doing? What is the difference in the values you are using to determine mesh sensitivity?

I am doing vortex shedding with suction and blowing. I am looking at COEFFICIENT OF LIFT & COEFFICIENT OF DRAG on the body to compare my result of different mesh. Generally the values converge as we increase the mesh size but in this case i am getting different different values as i am refining the mesh.
