**Figure 1.1-b: Diagram of thermal loads and geometry**

It is a metal beam (steel 1 6MND5, :math:`E={210.10}^{3}\mathrm{Mpa}`, :math:`\nu =0.2`) in bending. Elastic calculation (MECA_STATIQUE or STAT_NON_LINE) in plane stress modeling (C_PLAN). Meshes in TRIA3/SEG2 (modeling A) and TRIA6/SEG3 (models B and C).

The various key areas of the calculation are designated: GM14 for the entire volume part in TRIA, GM13 for the embedment (DDL_IMPO DX=DY=0 for all points :math:`(X=\mathrm{0,}Y=0\dots 10)`), GM12 for the distributed pressure (PRES_REP =0.1N for all points :math:`(X=50\dots \mathrm{100,}Y=10)`) and GM10 (mesh-point) :math:`\mathrm{M1}=\mathrm{N2}` at the point :math:`(X=\mathrm{100,}Y=0)` where we will measure the arrow).


Material properties

Material characteristics are applied throughout the structure (GROUP_MA GM14)

Boundary conditions and loads

The breakdown of loads by zone can be summarised in the form of the following table:

    "**Geometric areas (** **GROUP_NO/GROUP_MA/** ****) **", "**Loads**"
    "GM13 "," DDL_IMPO
    DX=0, DY=0"
    "GM12 "," PRES_REP = 0.1N"
