     Description :                                                       
     ___________                                                         
                                                                         
     The BGMO operator evaluates the functions appearing in the
     cement paste decalcification model by Bruno Gerard. These
     functions, varying with the temperature, are the capacity,
     the conductivity and their derivatives with respect to the
     temperature. Despite these functions are dimensional, the
     operator is also able to work in adimensional problems.

     This operator also features the coupling functions describing
     the interaction between the chemical problem and the mechanical
     one. These functions are (1-CHD) where CHD is the chemical damage,
     and the conductivity due to the mechanical damage.

     __________                                                        


      MOT1  : 'COND' for the conductivity
              'DCON' for the derivative of the conductivity
              'CAPA' for the capacity
              'DCAP' for the derivative of the capacity
              'CHED' for one minus the chemical damage
              'CONM' for the conductivity due to mechanical damage
      OBJ1  : REEL or MCHAML describing the temperature
      VAL1  : reference temperature (REEL). If not provided,
              it is set to 1.. If 'CONM' is used, the argument of
              the function is a normalized damage and this value is
              not used.
      VAL2  : reference conductivity/capacity (REEL). If not provided,
              it is set to 1.. If 'CHED' is used, the result is a
              normalized damage and VAL2 is not used.
      OBJ2  : REEL or MCHAML resulting from the evaluation


      Notes :
      _______


      The units used are meters, years and mmol/l.
      The temperature/concentration should range from 0 to 20 mmol/l.
      Damage values range from 0 to 1.
