v2.01.032 SDLD32 - Elementary validation of the schema in HHT time

Summary:

This test case allows you to validate the programming of the integration diagram in time HHT (Hilber-Hughes-Taylor) in « DYNA_NON_LINE » (« SCHEMA =” HHT “with" MODI_EQUI =' OUI'). It involves a simple problem, namely a system with one degree of freedom.

Two schemes are tested, namely the classical HHT scheme originally introduced in [bib1] (SCHEMA =' HHT '``with "MODI_EQUI =' OUI'), and the proposed version without overshooting of the schema HHT in [bib2] (SCHEMA =' NOHHT ').
