      While performing 2 Way FSI, I encountered the following error in the first iteration which is depicted in the following screenshot. Can anyone help me to solve this problem?

      Hi,

      The message means that at least one part in your model does not have enough constraints on it. The solver is producing a displacement of more than 1e6 length units which indicates that it is not solvable. Either add constraints until the message goes away or perform a modal analysis and look for the rigid body mode.

      Hope this helps!

      Regards,

      Rahul
