v5.01.122 SDND122 — Nonlinear mode calculation — system with 1 degree of freedom impacting an elastic stop

Summary:

The objective of this test is to validate the non-linear mode calculation with the operator MODE_NON_LINE. Post-treatments are also carried out with CALC_STABILITE and REST_MODE_NONL.

An analytical solution linking frequency and energy is available in the case of a material point that impacts against an elastic stop.
