5. C modeling

5.1. Characteristics of modeling

Modeling A is resumed by modifying only the circular section which becomes variable. The diameter varies from 0.1 to 0.11 m while the thickness varies from 0.011 to 0.01 m.

5.2. Tested values

The test focuses on the frequency of the first coupled axial mode of the fluid-containing pipe. As the cross-section is variable, we can no longer compare ourselves to the reference solution and only the non-regression is verified for this modeling.
