Breakdown: 10 elements in the column and in the beam


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

Number of knots: 21

Number of meshes and types: 20 SEG2


Characteristics of the cross section mesh
-----------------------------------------------------

Number of fibers: 100 (divided into 10 on each side)

Number of meshes and types: 100 QUAD4


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

The results are obtained by an automatic division of the time step and with arc-length control of the overall displacement response of the structure.

notes
---------

Using the arc-length technique makes it difficult to define the reference value to be entered in the TEST_RESU command, since these values cannot be imposed. The tests were therefore done in reverse by choosing the displacement values as a parameter and the force value as the tested value (i.e. ETA_PILOTAGE).

It is this way of testing that explains the high differences observed in :math:`\mathit{DY}` at the last moments when the curves are superimposed perfectly.
