/*! @brief Sortie_libre_Gradient_Pression_libre_VEFPreP1B
 *
 *  This class derives from the class Neumann_sortie_libre.
 *
 *     It represents an open boundary with a computed pressure gradient condition.
 *     The flux_impose() function returns an external pressure value computed from the imposed pressure gradient
 *     and the interior pressure.
