Additionally, the formulas used are give in CFD-Wiki here. The Schlichting skin-friction formula, as desribed here (equation 21.16 footnote in Schlichting), is used to estimate the local skin-friction for a turbulent boundary layer on a smooth flat plate. The correlation is valid for Re < 10^9.

Compute Mesh Spacing for a Given Y+ for Viscous Flow in CFD. Now you can compute wall spacing while at your desk or while on the road with the Y+ Calculator for iPhone, iPad, or Android. This free app is a handy tool for calculating the grid spacing at a wall to achieve a target y+ value for viscous computational fluid dynamics (CFD) computations.

- And Why Does It Matter? In this blog post, we will describe what is y+, how does it physically relate to a turbulent boundary layer, how it can be calculated, and what are some recommended values of surface y+ that should be used for different turbulence models. Law of the wall - Wikipedia.

In this context, the following page explains how you can generate the desired y+ (yplus) value on SimScale and check if your settings are correct: Y+ (yplus) - Generate Wall Spacing for CFD Y+ Calculator & Formula Online Calculator Ultra. Understanding and calculating \ (Y+\) accurately is essential for the successful application of CFD analysis in various engineering and research fields, enhancing the design and optimization of fluid flow systems.
