Default Fluid Solid Interaction - divergence

Hi,

I am modeling a wind blade using Fluid Solid Interaction (FSI). I choose Fluid Analysis first.

At the first Solid Analysis, the displacements of the blade are zero. At the second Solid Analysis, the displacements of the blade are about what I expect they are. Afterwards, the displacements of the blade are getting bigger and bigger at each Solid Analysis…

Does anybody already have this problem?

Thank you for your help. Seb

Not sure, but it sounds like you need some form of relaxation between the CFD & FEA simulations, but i might be completely wrong!
