13. Q modeling#
13.1. Characteristics of modeling#
The modeling is D_ PLAN, only the edge of the frame is represented.
13.2. Characteristics of the mesh#
Number of knots: 396
Number of meshes and types: 320 QUAD4 for the plate and 32 SEG2 for the frame.

13.4. notes#
The results obtained are close to the external source to within 5% (code mean). The linear solver has no influence on the results.
This modeling validates the exclusion of nodes only from the friction resolution in continuous formulation.
