Reference problem ===================== Geometry --------- We consider a cube with side :math:`1m`. Material properties ---------------------- For models A, B, C, and D: .. csv-table:: ":math:`E=1\mathit{MPa}` ", "Young's module" ":math:`\mathrm{\nu }=0.15` ", "Poisson's ratio" For E, F, G, H, H, I, I, I, J, K, L, and M models: .. csv-table:: ":math:`E=1\mathit{MPa}` ", "Young's module" ":math:`\mathrm{\nu }=0.` ", "Poisson's ratio" Boundary conditions and loads ------------------------------------- On edge :math:`\text{HAUT}`, a displacement is imposed (see paragraph :ref:`2 `). On edges :math:`\text{BORDX}`, :math:`\text{BORDMX}`, :math:`\text{BORDY}`, :math:`\text{BORDMY}`,, :math:`\text{BORDZ}` and :math:`\text{ESCLAVE}`, pressure is imposed (see paragraph :ref:`2 `). Throughout the domain, a force of volume is imposed (see paragraph :ref:`2 `). Surface :math:`\text{MAITRE}`, which is paraboloid in nature, is described by the equation: .. math:: :label: eq-1 Z\ mathrm {=}\ mathrm {-} 0.2\ mathrm {\ times} (1. + {X} ^ {2} + {Y} ^ {2})\ mathrm {-} 0.3 Initial conditions -------------------- Néant .. _refheading__31295122:
