i have a question about to check Y+ values in spesific part not a whole of model in simulation?

You can use contour or drawing graph.

i simulate Flue gas dispersion from exhaust gas stack.
but Y+ value is alwasy bigger.
whats wrong?

If your solution have converged, I think you must refine mesh close to walls . Also you can use adapt option to refine mesh near walls.

yes my solution is converged.
but is still confused how to refine mesh close to walls?
