    -----------------   

    Description :
    ____________

    The XFEM operator enables the user to make the posttreatment
 of results obtained using the XFEM formulation.


    -----------------------------------------------------------------
    | 1st possibility : Physical displacement field reconstitution  |
    -----------------------------------------------------------------

    CHPO2 = XFEM 'RECO' CHPO1 MOD1 ;

    Description :
    ____________

    The XFEM operator combines the displacement unknowns in order to
  obtain the physical displacement field.


    Contents :
    _________

    CHPO1 : XFEM displacement field (UX, AX, B1X..) (CHPOINT type)

    MOD1   : Model with at least 1 XFEM subzone (MODELE type)

    CHPO2  : Physical displacement field (CHPOINT type)

    -------------------------------------------------------
    | 2nd possibility : Displacement of the crack lips    |
    -------------------------------------------------------

    CHPO2 CHPO3 = XFEM 'FISS' GEO1 CHPO1 MOD1

    Description :
    ____________

    The XFEM operator with the keyword 'FISS' enables gives the 
 displacement fields on the crack. These displacement fields can be
 used to plot the crack opening.


    Contents :
    _________

    GEO1   : crack mesh (MAILLAGE type)

    CHPO1 : XFEM displacement field (UX, AX, B1X..) (CHPOINT type)

    MOD1   : Model with at least 1 XFEM subzone (MODELE type)

    CHPO2  : Physical displacement field upper lip (CHPOINT type)

    CHPO3  : Physical displacement field lower lip (CHPOINT type)
