Loading and boundary conditions are modelled by:

  • Dirichlet condition (keyword DDL_IMPO):

  • Node \(\mathit{N04}\), \(x\mathrm{=}y\mathrm{=}0\),

  • Node \(\mathit{N02}\), \(x\mathrm{=}0\).

  • Neumann condition, surface forces (keyword FORCE_CONTOUR):

  • on the faces (skin elements): (1, 2), (2, 4), (4, 3) and (3, 1).
