5. C modeling#

5.1. Characteristics of modeling#

Type of modeling used: element MECA_HEXA20 (hexahedra with 20 knots)

Boundary conditions:

DDL_IMPO =

(GROUP_NO = “TOUT”, DZ = 0.)

FACE_IMPO =

(GROUP_MA = “X0”, DX = 0., DY = 0.)

Shear on face \(\mathrm{XL}\): FORCE_FACE = (GROUP_MA = “XL”, FY =

)

5.2. Characteristics of the mesh#

Number of knots: 815

Number of meshes and types: 96 HEXA20, 200 QUAD8
