v6.02.138 SSNL138 - Validation of the optimization algorithm under the constraint of inequalities of option DDL_STAB

Summary:

This test allows the validation 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 the constraints of inequalities. The option can be applied to a list containing any degree of freedom available in Code_Aster.
