I am new to ansys software, I am building a simple model
a vertical cylinder, but on the wall I want to add inflation to refine the mesh, I saw sth. about Y+, but it is for turbulance model ,right? so what kind of regulation shall I follow when I try to add inflation boundary on the wall? Is there any forumlas for the inflation length scale?
