v6.03.105 SNNP105 — Analysis of a square massif with a unit side by the Bielles-Tirants method

Summary

This non-regression test case makes it possible to validate the construction and optimization of a Bielles-Tirants model via the macro command CALC_BT [R7.04.06]. The Bielles-Tirants model is built from the results of plane modeling. Two optimization schemes were tested: optimization of element sections and optimization of element sections with topological optimization.
