11. H modeling#
11.1. Characteristics of modeling#
3D discretization of the beam with element HEXA8. The beam-wall contact is modelled by DEFI_CONTACT with the GCP method.
The initial conditions and the boundary conditions are imposed through groups of nodes:
PAROI |
(embedding the lower nodes of the contact element) |
PLANSYMX |
(symmetry conditions according to \(x\)) |
PLANSYMY |
(symmetry conditions according to \(y\)) |
NOBARRE |
(initial movements and speeds). |
11.2. Characteristics of the mesh#
Number of knots: 88
Number of meshes and types: 21 HEXA8
