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


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

The average deformation resulting from a transitory calculation is calculated on a physical basis. For the resolution of the system, a time discretization equal to :math:`0.1s` is chosen.

The operator OBSERVATION is also used for the surveys of displacement fields and deformation.


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

Knots: 1029

Meshes: 720 HEXA8


Tested sizes and results
------------------------------

The deformation value is tested at the nodes located at the free end of the beam at time :math:`t=1s`.
