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


.. _DdeLink__788_95659094411:

This modeling is a compression test with a deformation imposed on a confined cube (blocked transverse deformations).

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**,

**1.0**, **-10.0**,

**1000.0**, **-10.0)**,

**)**

L_ INST **= DEFI_LIST_REEL (**

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

**INTERVALLE =(**

**_F (JUSQU_A =** **1.0**, **NOMBRE =** **5**, **)**, **)**,

**_F (JUSQU_A =** **35.0**, **NOMBRE =** **340**, **)**) **,

**)**,

**)**

During the time interval [:ref:`0.0, 1.0 <0.0, 1.0>`] the load increases.

During the time interval [:ref:`1.0, 35.0 <1.0, 35.0>`] the load is kept constant.


Tested sizes and results
