**v3.02.109** SSLP109 - Validating a feature in option DDL_STAB
============================================================================

**Summary:**

This test allows the validation of a feature of option DDL_STAB of CRIT_STAB, which assesses the stability of equilibrium states found by the numerical simulation of non-conservative problems such as damage problems. This requires applying an optimization algorithm under inequality constraints. The option can be applied to a list containing any degree of freedom available in *Code_Aster.*
