7. Summary of results

It can be seen that the macro-command makes it possible to obtain the voltage given by the BPEL (guaranteed by the procedure implemented by CASTEM) with very good precision since the difference is less than \(\text{0.1\%}\), both with the Newton method and with the IMPLEX method. Moreover, the effect of the tension of the cables on the rest of the structure and in particular on the cables that are already stretched, is completely satisfactory since the difference between the reference solution and the Aster calculation is less than \(\text{1\%}\), while the reference mesh was quadratic and the calculation carried out here used linear meshes.

The results are the same whether the calculation is solved using Newton’s algorithm or with method IMPLEX. The introduction of a diffusion cone does not change the quality of the calculations.

We also note that it is possible to carry out successive tensions with cables modelled with the 2 available models BARRE and CABLE_GAINE.
