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
