1. Reference problem

1.1. Geometry

Point coordinates:

	\(O\)	\(A\)	\(B\)		\(C\)		\(D\)	\(E\)	\(F\)
\(x\)			\(\sqrt{2}\mathrm{/}2\)		0.5		0.4
\(y\)			\(\sqrt{2}/2\)			0.5	0.4
\(z\)

1.2. Material properties

\(E=1.\mathrm{Pa}\)

\(\nu =0.3\)

\(\rho \mathrm{=}1.\mathit{kg}\mathrm{/}{m}^{3}\)

1.3. Boundary conditions and loads

Simple press on the edge of the plate:

in all \(P\) points such as \(\mathrm{OP}=R\): \(u=v=w=0\)

FORCE_COQUE	Uniform pressure	\(P=1N/{m}^{2}\)
FORCE_COQUE	Normal distributed load	\(\mathrm{F3}=–1N/{m}^{2}\)
PESANTEUR	\(g=10m/{s}^{2}\) next \(Z\) from where	\(\mathrm{FZ}=\rho gt=–1N/{m}^{2}\)

These three charges lead to the same solution.
