    Description :
    _____________

    The HDEB operator creates the flow field from the TH field
(with TH unknown of the final problem). This operator is devoted to
the DARCY formulation resolved by a hybrid mixed finite element method.

    Contents :
    __________

       MODE1  : modeled structure (MMODEL type) , description of the
                DARCY formulation (cf. MODE).

       RIG1   : RIGIDITE type, DARCY subtype; Contains 'darcy'
                elementary matrices for hybrid elements (cf. MHYB).

       CHP1   : CHPOINT type; Contains the concentrations (or the head)
                for each element's center. The geometrical support of
                this field is TAB1.CENTRE. If the component's name of
                CHP1 is H, the component's name of CHP2 must be TH.
                In the other cases, CHP1 and CHP2 have the same 
                component's names.
                ( In a coupled calculation transport-chemistry, CHP1
                 is the concentration in solution.)

       CHP2   : CHPOINT type; Contains the TH solution (with TH unknown
                of the final system). The geometrical support of this
                field is the MAILLAGE FACE included in TAB1. One of the
                component's field name must be TH If the component's
                name of CHP1 is H.In the other cases, CHP1 and CHP2
                have the same component's names.

       RIG2   : RIGIDITE type, MASSE subtype; Contains 'mass'
                elementary matrices for hybrid elements (cf. MHYB).

       CHP3   : CHPOINT type, FX FY (FZ) components ; means volumetrics
                forces on each element. The geometrical support of this
                field is the MAILLAGE CENTRE included in TAB1. This
                argument is optional. It usually uses for resolution of
                pressure written DARCY problem.
                It must be associated with RIG2 argument.

       CHP4   : CHPOINT type; The geometrical support of this field is
                the MAILLAGE FACE included in TAB1. Contains the
                convective speed flux accross element's faces.

       CHP5   : CHPOINT type result ; Contains the average flow field
                for each element's face. The geometrical support of
                this field is the MAILLAGE FACE included in TAB1.
                If the component's name of CHP2 is TH the component's
                field name of CHP5 is FLUX. In the other cases, CHP1 
                and CHP5 have the same component's names.
