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.
