Detailed Description

This subroutine computes the dimensionless distance to the wall solving a transport equation.

This function solves the following transport equation on $\varia$ :

$\dfrac{\partial \varia}{\partial t} + \divs \left( \varia \vect{V} \right) - \divs \left( \vect{V} \right) \varia = 0$

where the vector field $\vect{V}$ is defined by:

$\vect{V} = \dfrac{ \grad y }{\norm{\grad y} }$

The boundary conditions on $\varia$ read:

$\varia = \dfrac{u_\star}{\nu} \textrm{ on walls}$

$\dfrac{\partial \varia}{\partial n} = 0 \textrm{ elsewhere}$

Then the dimensionless distance is deduced by:

$y^+ = y \varia$
