Class
    Foam::qgd::HbyUQHD

Group
    grpQGDCoeffs

Description
    Class for one of possible ways of $\tau$ calculating.
    in this case $\tau$ parameter is calculating by

    $$ \tau = \alpha \cdot \frac{h}{U_0} $$

    Where:

    $\tau$ is regularisation parameter, $\alpha$ is parameter
    which depends by user in constant foulder, $h$ is size of the mesh
    and $U_0$ is characteristic velocity
