4. B modeling

4.1. Characteristics of modeling

We use a 2D_ FLUIDE, D_ PLAN, 2D_, 2D_ FLUI_STRU, 2D_, D_ PLAN_ABSO and 2D_ FLUI_ABSO modeling in coupled linear dynamics (\((u,p)\) formulation). IFS

4.2. Characteristics of the mesh

The characteristics of the mesh are identical to modeling A (see paragraph 3.2).

4.3. 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 4.3-1 : Quantities tested for B modeling

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 A. In general, the values obtained are very similar with a maximum error of less than 1.e -08%.
