How do I know what values of the y+ lie between? F.ex it will lie in the range of 20 < y+ < 60? Does it depent on the size of the thing I am simulating, what fluid I am using etc.?
Should I adapt the obstacle and the wall above with different values, when I want to know about the values around the obstacle (2D channel flow, drag-coefficiant etc). I am not sure if I have understood it correctly.
Any help would be greatly appreciated! Thank you,
