Y+ calculator

This handy Y+ calculator estimates the required height of the first mesh cell off the wall to achieve a desired Y+, based on flat-plate boundary layer theory. The math behind the calculations is obtained from the 5th edition of Frank M. White’s “Fluid mechanics”. Frank M. White was an American engineer and Professor Emeritus of Mechanical and Ocean Engineering at the University of Rhode Island.
