Dear all,
I'm trying to calculate wet modes of a very large ship structure. In order to consider the influence of water in ship natural frequencies, I've modeled a portion of water around the hull, and I've tried to carry out a fluid-structure analysis. Since the ship FE model is very large, I've used a static reduction to solve the problem (ASET1). When I run the analysis using such reduction, the fluid is not coupled to the structure. Is it possible to carry out such coupled analysis using static reduction? If so, do I have to select master nodes in fluid too?
Thank you very much
Lorenzito
PS: I have already tried to solve the analysis using MFLUID and avoiding the explicit modelling of fluid, but I want to model the water around the hull for comparing the outcomes obtained in both methods.
