3.1. Characteristics of modeling#

Modeling COQUE_3D

Element MEC3QU9H (3D solid shell) - Regular mesh

_images/Object_11.svg

3.2. Characteristics of the mesh#

Number of knots: 320

Number of meshes and type: 64 QUAD9

The mesh is half as fine as that of the reference solution.

3.3. Tested features#

  • COQUE_3D modeling in geometric nonlinear.

  • The static algorithm for updating large rotations GROT_GDEP from STAT_NON_LINE.

3.4. Tested values#

History of vertical displacement \(\mathit{DZ}\) at the loaded node

Instant

Surface Force \(\mathit{fz}\)
