15. J modeling#

15.1. Characteristics of modeling#

3D discretization of the beam with element HEXA8. Beam-wall contact is modelled by DIS_CHOC in explicit dynamics.

This test validates macro command MACRO_BASCULE_SCHEMA.

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).

Number of knots: 88

Number of meshes and types: 21 HEXA8
