**v5.01.123** SDND123 — Linear mode calculation for a system with 2 degrees of freedom with an elastic bilateral stop
=========================================================================================================================

**Summary:**

The objective of this test is to validate the non-linear mode calculation with the operator MODE_NON_LINE.

The system is particularly validated with a non-linearity such as a bilateral stop.

Post-treatments are also carried out with CALC_STABILITE and REST_MODE_NONL.
