For a 3D Case
1. Click Display-> Contour-> Turbulence-> Y Plus of the surface of interest.
2. Turn off Node Value display.
3. You can now check if the minimum and maximum Y+ forms an appropriate range
For a 2D Case
1.Click Display-> Contour-> Turbulence-> Y Plus. You do not need to select any Surfaces
2.Turn off Node Value display
3.You can now check the value of Y+ (note to ignore the value of Y+ except for cells adjacent to the wall). In a fine mesh, a recommended value of 1 for Y+ in a fine mesh, and 30 to 500 for a wall function.
