Class
    Foam::fv::FixedValueConstraint

Description
    Constrain the field values within a specified region.

Usage
    For example to set the turbulence properties within a porous region:
    \verbatim
    porosityTurbulence
    {
        type            scalarFixedValueConstraint;
        active          yes;

        scalarFixedValueConstraintCoeffs
        {
            selectionMode   cellZone;
            cellZone        porosity;
            fieldValues
            {
                k           1;
                epsilon     150;
            }
        }
    }
    \endverbatim
