3. Modeling A

3.1. Characteristics of modeling

The beam is modelled by 5 linear elements MECA_POU_D_T_GD supported on SEG2 cells: which remain straight. The deformed one is therefore a pentagon.

3.2. Tested sizes and results

Identification	Reference
\(\mathrm{DX}\) \((\mathrm{N3})\)	—0.30
\(\mathrm{DX}\) \((\mathrm{N4})\)	—0.70
\(\mathrm{DX}\) \((\mathrm{N6})\)	—1.00

The parameters of the result data structure are also tested:

Identification	Reference
INSTpour NUME_ORDRE =1
ITER_GLOB for NUME_ORDRE =1	10

3.2.1. notes

For large rotation problems, static equilibrium is generally reached in a number of iterations of the order of 10.
