Modeling I
==============


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

We use 3D modeling for solid elements with method CONTINUE for the treatment of CONTACT between linear mixed elements and quadratic elements.


Characteristics of the mesh
----------------------------


.. csv-table::

    "Number of knots:", "227"
    "Number of meshes and types:", "16 HEXA20, 25 HEXA8, 32 QUAD8et 50 QUAD4"


The meshes are incompatible. The contact surfaces are made up of 5 QUAD4 elements in front of 4 QUAD8 elements. The integration diagram used is of the Newton-Cotes type coupled with a technique of subdivision into sub-elements.
