3. Modeling A

3.1. Characteristics of modeling

3D (HEXA27)

3.2. Characteristics of the mesh

Number of knots:	3927
Number of meshes and types:	400 HEXA27

3.3. notes

Boundary condition \(\varphi =0.\) is implicit on free edges.

Discretization of time: 24 intervals between \(0.\) and \(1.2s\):

from \(t=0.00\)	to \(t=0.02\)	:		4	intervals of 0.005	seconds.
from \(t=0.02\)	to \(t=0.05\)	:	3	3	0.01 intervals	seconds.
from \(t=0.05\)	to \(t=0.15\)	:	4	4	0.025 intervals	seconds.
from \(t=0.15\)	to \(t=0.4\)	:	5	5	intervals of 0.05	seconds.
from \(t=0.4\)	to \(t=1.2\)	:		8	intervals of 0.1	seconds.
