5. C modeling#

5.1. Characteristics of modeling#

We use a COQUE_SOLIDE model.

5.2. Characteristics of the mesh#

The mesh contains 2500 elements of type HEXA9.

5.3. Tested sizes and results#

We test the movement along the \(Z\) axis.

Identification		Reference type	Reference value	Tolerance
DEPL	\(X(\mathit{cm})\)
\(\mathit{DZ}\)	\(0.0\)	“SOURCE_EXTERNE”	\(0.1033\)	\(\mathrm{2,6}\text{\%}\)

We test the constraints on the mesh in the center in NON_REGRESSION:

\(\mathit{SIYY}\)	SurfSup	“NON_REGRESSION”

The deformation of thermal origin is tested at the center of the mesh, on the lower skin, for which we have an analytical reference value:
