Class
    Foam::nutLowReWallFunctionFvPatchScalarField
 
Group
    grpWallFunctions
 
Description
    This boundary condition provides a simple wrapper around a zero
    fixed-value condition for the turbulent viscosity (i.e. \c nut)
    for low-Reynolds number applications. It sets \c nut to zero,
    and provides an access function to calculate \c y+.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        type            nutLowReWallFunction;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                      | Type | Reqd | Deflt
      type      | Type name: nutLowReWallFunction  | word | yes  | -
    \endtable
 
    The inherited entries are elaborated in:
      - \link nutWallFunctionFvPatchScalarField.H \endlink
