Class
    Foam::fv::zeroDimensionalMassSource
 
Description
    This fvModel applies a mass source to the continuity equation and to all
    field equations, in a zero-dimensional case. Correction is made to account
    for the mass that exits the domain due to expansion in space, so that the
    model correctly applies a total mass flow rate.
 
    This model requires a corresponding field source to be specified for all
    solved-for fields.
 
    This model will write out additional fields, zeroDimensionalMassSource:m
    and zeroDimensionalMassSource:factor. The zeroDimensionalMassSource:m field
    is the total accumulated mass; the sum of the starting mass, plus all mass
    added by models of this type. This may differ from the actual current mass
    (= rho*V) within the zero-dimensional cell if pressure or density
    constraints are being used. The zeroDimensionalMassSource:factor field is
    the ratio between the current mass or volume and the total accumulated mass
    or volume.
 
Usage
    Example usage:
    \verbatim
    zeroDimensionalMassSource
    {
        type            zeroDimensionalMassSource;
 
        massFlowRate    1e-4;
    }
    \endverbatim
