C modeling
==============


Characteristics of modeling
-----------------------------------

Type of modeling used: element MECA_HEXA20 (hexahedra with 20 knots)

Boundary conditions:


.. csv-table::

    "DDL_IMPO =", "(GROUP_NO = 'TOUT', DZ = 0.)"
    "FACE_IMPO =", "(GROUP_MA = 'X0', DX = 0., DY = 0.)"


Shear on face :math:`\mathrm{XL}`: FORCE_FACE = (GROUP_MA = 'XL', FY =

NoteThis modeling is the one that is used as a reference for calculations with hexahedra with 8 nodes.
