      HOO1  =  HOOKE  MODL1  CAR1  (VAR1) ('REFE')  ;


    Description:
    ____________

    The HOOKE operator constructs the field of HOOKE's matrix
    from a field of material properties (and possibly geometrical 
    characteristics) 

      Contents :
      _________


      MODL1  :  model object (MMODEL type)

      CAR1  :  field by element of geometrical and material properties
               (MCHAML type, CARACTERISTIQUES subtype)

      VAR1  : field of internal variables (MCHAML type, 
              VARIABLES INTERNES subtype) 

      HOO1  :  field by element of Hooke's matrices (MCHAML type,
               MATRICE DE HOOKE subtype)



  Notes :
  _________

  In the case of endommageable and visco-endommageable materials, and if
  the field of internal variables is given, the HOOKE's matrix
  take care of the endommagement.

  CAR1 is required only for the types of elements whose complete 
  geometry cannot be deduced from the mesh, for instance, beam, 
  pipe, or shell elements.

  For the offset thin shell type elements, the word 'REFE' may be
  specified for getting Hooke's matrices that are associated
  with magnitudes (efforts and deformations) defined at the level of
  the surface of reference. Otherwise, the matrices correspond to 
  magnitudes defined at the level of the offset surface.
 
  For the orthotropic DST element, HOO1 also contains 
  the direction cosines of the axes of orthotropy with respect to
  the element local axes.
