Two approaches were tested in this validation case: Wall functions and full resolution on the walls. For the wall functions, the desired \(y^+\) range is [30 , 300], and the generated mesh looks like this:
Full resolution on the walls requires a \(y^+\) lower than \(1\), so the final mesh has the following form:
