v2.04.105 SDLV105 — Modal analysis of a main primary circuit with IFS

Summary:

This test carries out the modal analysis of a primary circuit taking into account fluid-structure interaction.

The following models are presented:

• modeling A: modal analysis by dynamic substructuring (see [U2.07.07] for a description of the methodology);

• B modeling: modal analysis of the global problem with elimination of Lagrange multipliers (see [R3.03.05] for a description of the methodology).
