**v5.02.137** SDNL137 — Calculation of non-linear modes of a bent pipe with two annular contact type nonlinearities
=========================================================================================================================

**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 nonlinearity of the annular contact type.
