Modélisation D
==============


Caractéristiques de la modélisation
-----------------------------------

Cette modélisation est un essai de compression en déformation imposée, sur un cube confiné.

Le chargement est imposé sur la face HAUT suivant DZ:

**DDL_IMPO =** **_F(GROUP_MA=’HAUT’** , **DZ =** **1.0E-04)** ,

FCT **= DEFI_FONCTION(**

**NOM_PARA =** **’INST’** ,

**VALE =** **(0.0,0.0** ,

**10.0** , **-70.0** , **)** ,

**)**

L_INST **= DEFI_LIST_REEL(**

**DEBUT =** **0.0** ,

**INTERVALLE =** **(**

**_F(JUSQU_A=** **10.0** , **NOMBRE =** **100** , **)** ,
