B modeling ============== Characteristics of modeling ------------------------ The lyre is divided into 2 substructures, meshed in an identical manner and therefore conformal. Moreover, the problem is solved on a global network. This makes it possible to compare the 2 approaches by calculating the MAC criterion (Modal Assurance Criterion). Characteristics of the mesh ---------------------------- Lyre 1 Number of knots: 6936 Number of meshes and types: 1080 SEG2, 4250 QUAD4 and 6250 HEXA8 Lyre 2 Number of knots: 6936 Number of meshes and types: 1080 SEG2, 4250 QUAD4 and 6250 HEXA8 Lyre global Number of knots: 12376 Number of meshes and types: 1880 SEG2 ,7450 QUAD4 and 11250 HEXA8 Tested sizes and results ------------------------------ We test the values of the MAC matrix.
