    (RIG2) (CHP3) = SMTP MODE1  RIG1 (TAB2) (CHP1) (CHP2) ;


    Description :
    _____________

    The SMTP operator creates the contribution to the TH system
(with TH unknown of the final problem) due to sources and convection.
This operator is devoted to the resolution of convection-diffusion
equation by a hybrid mixed finite element method (DARCY modelisation).


    Contents :
    __________

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

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

       TAB2   : TABLE type, DARCY_TRANSITOIRE subtype. Contains initials
                fields and numericals coefficients for the
                discretization time scheme (cf darcytra procedure).

       CHP1   : CHPOINT type; Contains the integral of the source term
                over each element. The geometrical support of this
                field is the MAILLAGE CENTRE. The  component's field 
                name is SOUR.

       CHP2   : CHPOINT type; Contains the flux of convection-speed
                through each face. The geometrical support of this
                field is the MAILLAGE FACE. The component's field
                name is FLUX.

       CHP3   : CHPOINT type result ; Contains the assembled right hand
                side. The geometrical support of this field is the
                MAILLAGE FACE. The component's field name is FLUX.
                In stationary, CHP3 exists only if CHP1 is given.
                In transient, CHP3 always exists.

       RIG2   : RIGIDITE type, CONVEFMH subtype; Contains convection
                elementary matrices. RIG2 exist only if CHP2 is given.
                In transient, RIG2 don't exist in explicit formulation.
