6. D modeling

6.1. Characteristics of modeling

The overall mesh of the lyre is used. Boundary conditions are imposed by elimination (see [U2.01.02]). The simulation is launched on 4 processes on which the mesh is cut and distributed.

6.2. Characteristics of the mesh

Lyre global

Number of knots: 12376

Number of meshes and types: 1880 SEG2, 7450 QUAD4 and 11250 HEXA8

6.3. Tested sizes and results

Non-regression values of the calculated natural frequencies are tested.
