E modeling
==============


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

A 3D modeling with elements HEXA8 testing the functionalities of node-mesh contact with friction treated with the continuous method for contact friction has been implemented.

The game between the skate and the frame is defined by a function using the keyword "DIST_2".

To avoid rigid body movements, the skate is held in place by springs of low stiffness:

    "RES_LAT ", ": :math:`k\mathrm{=}1N\mathrm{/}\mathit{mm}`"
    "RES_FOND ", ": :math:`k\mathrm{=}1N\mathrm{/}\mathit{mm}`"
    "RES_HAUT ", ": :math:`k\mathrm{=}20N\mathrm{/}\mathit{mm}`"


Boundary conditions:

Free end of the springs: :math:`\mathrm{DX}=\mathrm{DY}=\mathrm{DZ}=0`.

Built: :math:`\mathrm{DX}=\mathrm{DY}=\mathrm{DZ}=0`.
