2. Modeling A

2.1. Characteristics of modeling

The modeling is based on the dynamic substructuring approach described in [U2.07.07]. The components and pipes are divided into 23 substructures.

2.2. Characteristics of the mesh

Due to the complexity of the meshes used, the details are not provided.

2.3. Tested sizes and results

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