**v1.01.231** ZZZZ231 — Contact validation in initial geometry
===================================================================

**Summary:**

This test is an analytical test. The tests are done on trips only. The objective is to validate for discrete contact formulations:


* the correct consideration of contact in initial geometry (REAC_GEOM =' SANS ') when restarting the calculation (reuse =)


* the correct consideration of contact in initial geometry (REAC_GEOM =' SANS ') with initial state (ETAT_INIT)


* the calculation of the game using the 'RESOLUTION =' NON" method

Modeling A:


* Reference calculation in method 'CONTRAINTE', calculation of the game in method 'RESOLUTION =' NON ", discrete and continuous formulation

Modeling B:


* Calculation in initial geometry with resumption

C modeling:


* Calculation in initial geometry with initial state
