Modeling 3D

3.2. Characteristics of the mesh

The mesh contains 1 element of type HEXA8.

3.3. Quantities tested and results of modeling A

Identification	Reference	Test	Tolerance
\(\varepsilon\) out of \(\mathit{NO1}\) to \(t\mathrm{=}\mathrm{1s}\)	0.07830	ANALYTIQUE	0.11%
\(\gamma\) on \(\mathit{NO1}\) to \(t\mathrm{=}\mathrm{1s}\)	0.11700	ANALYTIQUE	0.20%
\(p\) out of \(\mathit{NO1}\) to \(t\mathrm{=}\mathrm{1s}\)	0.15260	ANALYTIQUE	0.10%
\({\sigma }_{11}\) out of \(\mathit{NO1}\) to \(t\mathrm{=}\mathrm{1s}\)	409.70700	ANALYTIQUE	0.05%

The parameters of the result data structure are also tested:

Identification	Reference	Test	Tolerance
INSTpour NUME_ORDRE =8	1	ANALYTIQUE	0%
ITER_GLOB for NUME_ORDRE =8	4	NON_REGRESSION	0%

3.4. notes

We would expect better correlation, but it should be noted that library NAG uses the function

in algebraic form, while*Code_Aster* uses it in the form of a curve given point by point.

In addition, it seems that integrating the threshold function rate is causing problems for NAG, regardless of the precision otherwise required (the threshold value

being significantly different from 0 at the end of integration). However, we can note the consistency of this correlation throughout the integration
