**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 [:external:ref:`R7.04.06 <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.
