solaris New Member Join Date: Dec 2016 Posts: 13 Rep Power: 9	Hello, I'm trying to model mixed convection in an air duct, I'm using the laminar equations because Re is very low but the flow is unstationary, in this case what is the criterion to figure out if the mesh is ok (in turbulent flows it is y+)? because I'm guetting different results with different meshes even if the convergence is reached with each one, some help ? Thanx
