Hi all,
Could you answer on my question, I just need to know how to set timestep in Star-CCM+? I need that my simulation will be done in for ex. 100 timestep, and after I want a finally result, finished result when i set different tstep results of the same simulation are not the same Could you explain thx Aika |

You need to check the courant number.

thx a lot amir
I have another question, how I can set pressure difference between min 60000Pa and max 101000Pa when I set like this my results have changed totally I have an experimental data, velocity = 0.38 mass flux=0.02 kg/sec and pressure difference 60000<pres<101000 after I need to obtain the result, but I have no the same result like experimental data I simulate a cyclone thx Aika |

I think you need to set the inlet boundary conditions and put the pressure outlet for your outlet, and if your mesh and other things would be right, you should be able to obtain the similar pressure drop and experimental values that you have.
