3. Modeling A

3.1. Modelling characteristics: d-plan (QUAD4 + TRIA3)

Boundary conditions:
side \(\mathrm{AB}\)	DDL_IMPO = (GROUP_NO = bordAB DY = 0.)
side \(\mathrm{EF}\)	FACE_IMPO = (GROUP_MA = faceEF DNOR = 0.)
press on the face \(\mathrm{AE}\)	PRES_REP = (GROUP_MA = faceAE PRES = 60.)

Node names:	\(A=\mathrm{N23}\)	\(B=\mathrm{N1}\)	\(C=\mathrm{N391}\)
	\(D=\mathrm{N369}\)	\(E=\mathrm{N451}\)	\(F=751\)

3.2. Characteristics of the mesh

Number of knots: 759

Number of meshes and types: 704 TRIA3, 352 QUAD4

3.4. notes

The increase in the error, when we go from \(\mathrm{AB}\) to \(\mathrm{CD}\) and then \(\mathrm{EF}\), is due to the mesh (element density QUAD4 lower than in TRIA3).
