Grid Spacing in mesh

Hello everyone, Currently I am working on rocket nozzle. Before starting my actual simulation, I want to be sure on mesh?. I read different blogs and came to know that I have to look for the boundary layer, grid convergence, and grid spacing. I need help to be sure on these topics.

    I'd start by reading a book on CFD modelling, that'll explain the various concepts. That'll also give you some pointers to things like y+ and mesh independence studies. From there, do the tutorials that you'll find in the Fluent (online) help.
