Class
    Foam::interstitialInletVelocityFvPatchVectorField

Description
    Inlet velocity in which the actual interstitial velocity is calculated
    by dividing the specified inletVelocity field with the local phase-fraction.

    Example of the boundary condition specification:
    \verbatim
    inlet
    {
        type              interstitialInletVelocity;
        inletVelocity     uniform (0 0.2 0);// Non-interstitial inlet velocity
        alpha             alpha.particles;  // Name of the phase-fraction field
        value             uniform (0 0 0);
    }
    \endverbatim
