Allow specifying a target yPlus

This would automatically adjust the blockMeshDict based on the Blasius boundary layer solution and the kinematic viscosity. Note that the free stream velocity should probably stay 1 for simplicity.

You can use this to calculate k omega epsilon from the U stram velocity

From there, you can also calculate the first cell height.

When you have it, you can put in
https://github.com/Carlopasquinucci/BlockMeshCellDimension/blob/master/blockMeshCell.py

and calculate the dimension of the blockMesh cell

Here you have an automatic toll for meshing, starting from velocity and turbolnet lenght scale
