## What is yPlus Calc?

This app provides an straight-forward tool for engineers, scientists and students performing viscous CFD computations to calculate preliminary Y Plus values and first mesh elements layer spacing on SI units during mesh generation.

The calculations are based on flat-plate boundary layer flow theory, and Skin-Friction coefficient can be calculated using the following formulae:

 - 1/7 Power Law;
 - "Prandtl (1927)";
 - "Prandtl-Schlichting (1932)";
 - "Hughes (1954)";
 - "ITTC (1957)".
