Grid-independent validation Criteria

      Grid-independent validation is required before using steady to calculate the flow field, but the parameters selected in this state are not final.
      How should I perform mesh-independent validation? Is it possible to use different grids, the same equation parameters, and the same steps? Do I have to be in a converged state when making the judgment? Can I run the same step, but not yet in a converged state, and then judge the results?

      Hello,

      Yes, that's true. You need to compare the parameters which are of interest to your study and also at the region of interest. Yes. Use same equation parameters at same steps in the converged state. You need to be converged in each step as well as in time step to make the judgement.
