4. Summary of results

This test case makes it possible to verify the behavior of the various fluid-structure coupling calculation operators, in the case of multiple excitation zones. It is a test case of non-regression of the operators concerned, and in particular, of the data structures.

In the case of fluid-elastic forces (operators DEFI_FLUI_STRU and CALC_FLUI_STRU), when several fluid excitation zones are defined with identical characteristics, rigorously equivalent results are obtained in the case where there is only one zone.
