5. C modeling

5.1. Characteristics of modeling

3D elements (TETRA4)

along the \(Z\) axis: 2 layers of elements total thickness: 0.01

Boundary conditions:

	DDL_IMPO:	(All: “yes”	Dz: 0.)
face \(\mathrm{AB}\)		(group_no.Bordab	Dy: 0.)
face \(\mathrm{EF}\)	FACE_IMPO:	(group_ma:faceef	Dnor: 0.)
press on the face \(\mathrm{AE}\)	PRES_REP:		(group_MA:faceAE	Press: -1.)

Node names:	A=No3	B=No3	B=No7	C=No4	D=No8	E=No154	F=No156
plane \(z=0.005\)	A2=No1	B2=No5	B2=No5	C2=No2	D2=No6	E2=No153	F2=No153	F2=No155
plan \(z=0.01\)	A3=No283	B3=No285	C3=No284	D3=No286	E3=No359	F3=No359	F3=No360

5.2. Characteristics of the mesh

Number of knots: 423

Number of meshes and types: 1416 TETRA472 TRIA3

5.3. notes

Pressure has a negative sign (instead of positive) because the faces of the \(\mathrm{3D}\) elements are misoriented.

5.5. notes

We note a variation (\(\text{< 0.24\%}\)) in the movements for the points of the \(z=0.005\) plane.

The mesh is insufficient for linear elements.
