CFView: Unsteady state visualiation

Please specify which software you are using, Fine/Turbo or Fidelity, along with the version. If you are using Fine/Turbo, then in the CFView, click on the "Geometry" tab. You can locate this tab at the top of the toolbar. Now, you have two options: "Repetition on/off" and "Repetition Number," which you can select accordingly.

I am using FINE/Turbo CFView. This is an unsteady simulation, and I want to see the rotor in different positions relative to the stator (different time steps?).

Do I have to enable the Multiple files option? When I ask CFView to read the result file, it doesn't ask me what time step I want to as it says in the manual. It just opens a file with the rotor in the position that it ended.

Also, is there anywhere on the manual convergence criteria for unsteady simulation on FINE/Turbo?

Hi, Yes, you need to choose the "Multiple Files" option to visualize the rotor's rotation. I do not understand what you are trying to say "Manual convergence criteria".

Thank you.

I wanted to ask if the Fine/Turbo user guide contains any information about convergence criteria for unsteady.

Hi,

As described in the user guide of Fine Turbo, it is important to reach convergence for each inner iteration. The criterium can be defined in the interface. However, it is often a good idea to base the judgement of convergence not just on the residuals but also on a relevant quantity in one or multiple control points.

If the inner iterations are well converging, it is then important to run sufficient periodic cycles to get a converged unsteady solution: the solution over one period is reasonably the same compared to the previous period.
