Class
    Foam::fv::FixedValueConstraint
 
Group
    grpFvOptionsConstraints
 
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;
 
        selectionMode   cellZone;
        cellZone        porosity;
        fieldValues
        {
            k           1;
            epsilon     150;
        }
    }
    \endverbatim
