		+	While performing CFD simulations, it is critical that one capture boundary layer near the wall properly. In order to do that, the mesh should be generated in such a manner that it captures boundary layer properly. For turbulent flows, calculation of the [[Dimensionless wall distance (y plus) \| Y plus]] value of the first interior node/gridpoint helps in doing that. This dimensionless distance is defined as
		+
		+	:<math>y^+ := \frac{u_* \, y}{\nu}</math>
		+
		+	where <math>u_*</math> is the friction velocity defined as
		+
		+	:<math>u_* := \sqrt{\frac{\tau_w}{\rho}}.</math>
		+
		+	The [[Wall shear stress\|wall shear]] <math>\tau_w</math> can probably not be determined until after a simulation has been completed, so it is usually necessary to estimate a value, and then check after a simulation is complete.
