5. C modeling

5.1. Characteristics of modeling

The overall mesh of the lyre is used. Boundary conditions are imposed by dualization (see [R3.03.01]). The simulation is launched on 4 processes on which the mesh is cut and distributed.

5.2. Characteristics of the mesh

Lyre global

Number of knots: 12376

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

5.3. Tested sizes and results

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