Class
    Foam::nutLowReWallFunctionFvPatchScalarField
 
Group
    grpWallFunctions
 
Description
    This boundary condition provides a wall constraint on the turbulent
    kinematic viscosity, i.e. \c nut for use with low Reynolds number models.
    It sets \c nut to zero, and provides an access function to calculate \c y+.
 
Usage
    \table
        Property     | Description                 | Required  | Default value
        Cmu          | Model coefficient           | no        | 0.09
        kappa        | Von Karman constant         | no        | 0.41
        E            | Model coefficient           | no        | 9.8
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        type            nutLowReWallFunction;
 
        // Optional entries
    }
    \endverbatim
