I'm wondering if Ansys Fluent does simulation on sub-levels of the assigned grid to check the grid convergence. If the answer is no, how do it check for grid convergence? Browsing through the tutorial I didn't find many answers
thanks for the supporting.

I think the way for you is grid indepenence test, if I got your question correctly

AFAIK Fluent does not conduct grid independence tests. During the pre-processing you should build your different meshes (coarse, base, fine, etc..) and then, run the simulations. In other words, you need to do this study yourself! Here is an excellent reference on how to perform these tests with the GCI method https://doi.org/10.1115/1.2960953
