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

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

3D modeling

Item MECA_HEXA8


Characteristics of the mesh
----------------------------

Number of knots: 8

Number of meshes and type: 1 HEXA8

Tested sizes and results

The deformations, the stresses and the damage value are compared at 3 different time steps (at the end of stage 1, during the growth phase of the damage and at the end of the loading).
