    Description :
    ____________

    The CAPACITE matrix creates a calorific capacity matrix.

    Contents :
    __________

    MMODE1 : modeled structure (MMODEL type)

    CAR1   : object containing the structure physical
             characteristics (MCHAML type, CARACTERISTIQUES
             subtype)

    TAB1   : table (TABLE type) containing the information relative
             to the change of phase, with the following indices :

      'SOUSTYPE'         : 'THERMIQUE' (MOT type)
      'CHALEUR LATENTE'  : latent heat of the change of phase
                                   (FLOTTANT type)

      'TPHASE 1'         : temperature 1 of the change of phase
                                   (FLOTTANT type)
      'TPHASE 2'        : temperature 2 of the change of phase
                                   (FLOTTANT type)
      'CHAMP THERMIQUE 1': température au debut du pas
                                   (CHPOINT type)
      'CHAMP THERMIQUE 2': température a la fin du pas
                                   (CHPOINT type)

    CAP1   : calorific capacity matrix (RIGIDITE type)

    Note :
    ________

    In the general case the capacity matrix is the integration of 
    tN . RHO . C . N . DV where N is the matrix asssociated with
    the interpolation functions. (RHO is the density).

    The change of phase is progressive between the temperatures 
    TPHASE 1 and TPHASE 2. The variation of the enthalpy function 
    for the complete change is:
             CHALEUR LATENTE +C.( TPHASE 2 - TPHASE 1)
    where C is value extracted from CAR1.
    TPHASE 1 and TPHASE 2 must not be equal.

    When TAB1 is specified the heat capacity matrix is an apparent
    heat capacity matrix defined as the derivative of the volumic
    enthalpy between temperatures CHAMP THERMIQUE 1 and 
    CHAMP THERMIQUE 2.
