6. D modeling#
6.1. Characteristics of modeling#
The modeling is D_ PLAN, only the edge of the frame is represented. Two calculations are performed with different pairing options, contact algorithms, and linear solvers.
6.2. Characteristics of the mesh#
Number of knots: 763
Number of meshes and types: 325 TRIA6 for the plate and 32 SEG3 for the frame.

6.4. notes#
The results obtained are close to the external source to within 5% (code mean). The linear solver has no influence on the results.
