Modal Analysis of a Box with Fluid

Hi,

 

I would like to compute normal modes of a closed box filled with a fluid by using Optistruct. I use the ACMODL card to define the fluid structure interfaces and the EIGRL method to compute the normal modes. As a result I obtain the normal modes computed separately, on the one hand for the structure and on the other hand for the fluid. Is there any possibility to compute the normal modes for the coupled system?

Thanks in advance.
