v2.03.103 SDLS103 - Coaxial shells under annular flow: inertial coupling between modes

Summary

We consider a hardware configuration consisting of two coaxial cylindrical shells, interacting with a fluid flowing in the annular space separating the shells.

The aim of the test case is to validate the fluid-structure coupling model developed in operator CALC_FLUI_STRU for this type of configuration.

Here, we are more particularly interested in taking into account the inertial coupling between modes, obtained in water at rest (mean flow speed zero). The reference solution is provided by a calculation performed with Code_Aster using the CALC_MATR_AJOU operator.
