Bold values indicate >5% change in values. The degrees of freedom indicated are U_x is velocity in the main direction of flow (horizontal), U_y is the lateral velocity, U_z is the vertical velocity, KE is the turbulence kinetic energy, E is the dissipation of turbulence kinetic energy, and SP is the pressure.
