5. C modeling

5.1. Characteristics of modeling

We use a 3D_ FLUIDE, 3D, FLUI_STRU,,, 3D_,, 3D_ ABSO and 3D_ FLUI_ABSO modeling in coupled linear dynamics (formulation \((u,p)\)). IFS

5.2. Characteristics of the mesh

The mesh is generated by extruding the 2D mesh of the A and B models of a single element into the depth. This mesh contains 908 linear hexahedra, 324 linear prisms, and 2302 nodes.

5.3. Tested sizes and results

We test the accelerations at time \(t=0.98s\) at the post-processing points for the X and Y directions:

Table 5.3-1 : Quantities tested for modelling C

Identification	Reference type
A-AX node	AUTRE_ASTER
A-AY knot	AUTRE_ASTER
B-AX node	AUTRE_ASTER
B-AY knot	AUTRE_ASTER
C-AX node	AUTRE_ASTER
C-AY knot	AUTRE_ASTER
D-AX node	AUTRE_ASTER
D-AY node	AUTRE_ASTER

These values are compared directly with the solution obtained in modeling B. In general, the values obtained are practically identical with a maximum error of less than 1e-08%.
