**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 [:ref:`bib1 <bib1>`] 
(``SCHEMA =' HHT '``with "MODI_EQUI =' OUI'``), and the proposed version without overshooting of the schema HHT 
in [:ref:`bib2 <bib2>`] (``SCHEMA =' NOHHT '``).
