Inquiring for the perspective of fluid-structure interaction
Hello everyone, I am researching fluid-strucrure interaction (FSI) and its algorithms using CFD and computational solid mechanics (CSM), I have already spent two years to develop FSI programs, and now these codes can be used to solve some engineer problems. However, I am not sure that the future of FSI especially FSI research is sound, my reasons include the precision, robustness and reliability of CFD and CSM are not satisfactory, especially considering aerodynamic heating, or damage and contacting, etc. Moreover, the coupling of CFD and CSM will bring more other monumental difficulties. From another point of view, some commercial softwares which utilize mature algorithms have already been introduced to the market.
Now, I am puzzled. Can anyone tell me the future of FSI research and how to keep a step ahead of engineering?

there in no difficulties, use Riemann's solver

FSI in LS-DYNA
Recently, I started working on fluid structure interaction (FSI) problems. Among the commercial codes, LS-DYNA offers the most robust FSI solution methods. Some information on FSI using LS-DYNA can be found at http://www.lsdyna-portal.com/index.php?id=3994
Following papers can also help. I would love to know what other researchers think about FSI using LS-DYNA.Aquelet, N. and M. Souli, A new ALE formulation for sloshing analysis.
