Following axis \(Z\):	1 layer of elements
Total thickness:	1
Boundary conditions:
Knot \(A\) Bow \(E\) Bow \(D\) Bow \(H\)	\(\mathrm{DX}=\mathrm{DY}=\mathrm{DZ}=0.\) \(\mathrm{DX}=\mathrm{DY}=0.\) \(\mathrm{DX}=0.\) \(\mathrm{DX}=0.\)
press on the face \(\mathrm{BCFG}\)	\(F=220.\mathrm{MPa}\)

3.2. Characteristics of the mesh
