Description🔗

The nutLowReWallFunction is boundary condition that provides a simple wrapper around a zero fixed-value condition for the turbulent viscosity (i.e. nut) for low-Reynolds number applications. It sets nut to zero, and provides an access function to calculate y+.

Usage🔗

The condition requires entries in both the boundary and field files.

Boundary file🔗

<patchName>
{
    type            wall;
    ...
}

Field file🔗

<patchName>
{
    // Mandatory entries
    type            nutLowReWallFunction;

    // Inherited entries
    ...
}

where:

The inherited entries are elaborated in:

• nutWallFunctionFvPatchScalarField.H
