Modeling A
==============


Characteristics of modeling
-----------------------------------

This modeling is a tensile test under imposed deformation, on a cube that is free to deform in the direction perpendicular to the load.

The load is imposed on side HAUT following DZ:

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

FCT **= DEFI_FONCTION (**

**NOM_PARA =** **' INST '**,

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

**10.0**, **3.0**, **)**,

**)**

L_ INST **= DEFI_LIST_REEL (**

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

**INTERVALLE =** **(**

**_F (JUSQU_A =** **10.0**, **NOMBRE =** **50**, **)**, **)**,

Tested sizes and results
------------------------------

The observed quantity is the constraint SIZZ on the HAUTE face.
