4. B modeling#

4.1. Characteristics of modeling#

The beam part is modelled by elements from TUYAU. The shell part is modelled in DKT.

4.2. Characteristics of the mesh#

Number of knots: 4420

Number of meshes and types:

  • 1 mesh POI1 (modeling DIS_TR),

  • 1344 QUAD4 stitches (DKT modeling), 32 SEG2 stitches on each edge of the shell

  • 4 SEG3 (TUYAU) stitches

4.3. Tested values#

Displacements and rotations at point \(\mathrm{P2}\) (to be multiplied by \(1.E-10m\)).
