      There are two wall treatment options in CFX solver, which are similar to those in fluent: 1: If the user chooses Default, it means the grid is a low-Reynolds number grid, then the requirement is y+ < 1. 2: If the user chooses Scalable, it means the grid is suited for a log-law wall function, then the requirement is y+ >30. 3. It can be found in the Turbulence Options as Eddy Viscosity Transport Equation.
