Dear all,

I have a very fundamental question. I have some experimental data that I would like to validate my CFD results against. Should I test my CFD solution for grid independence? Or would an adequate comparison with the experimental data be sufficient enough to call the CFD solution (with a grid not tested for independence) a representation of what's happening within the system?

In other words, should only a grid independent solution used for validation against experimental data? Or can a solution that provides adequate agreement with experimental data be deemed as final (without doing any grid independce studies)?

I would appreciate your response.

Thank you.
