17. Y modeling#

17.1. Characteristics of modeling#

The modeling is 3D, only the edge of the frame is represented.

17.2. Characteristics of the mesh#

Number of knots: 792

Number of meshes and types: 320 HEXA8 for the plate and 32 QUAD4 for the frame.

17.3. Tested sizes and results#

First calculation (formulation “CONTINUE”, solver “MULT_FRONT”, algorithm “PENALISATION”).

17.4. notes#

The results obtained are close to the external source to within 5% (code mean). Choosing the right penalty coefficient is essential to have a good quality of solution.
