I am trying to simulate Fluid Structure Interactions on ANSYS with fluent, transient structural and system coupling. My model is set to simulate flutter - a bar of aluminum passing through multiple sections of airfoils (to induce flexibility) and a weight at the top to add inertia. Everything is good until I update the solution in the system coupling module. I am having issues with convergence and would appreciate any feedback on my setup (it diverges at the first time step - 0.1 second). I have dropped the time step to 1e-08 and I still have the same error. Any help will be greatly appreciated.
