[Newbie] Need help simulating an air bubble moving in a tube

This is a relatively simple model. 2-d axisymmetric tube with an ellipse cut out of it to simulate a narrowing of the tube. I have a circle to simulate the air bubble. (it's only half a circle since its axisymmetric) I am performing fluid structure interaction physics with the structure being the air bubble. I am doing a time dependent study to see the movement of the bubble through the tube. When I attempt to compute the study, I receive an error. "Recoverable error in residual, but solver could not recover.
Time : 0.04044302267723873 Last time step is not converged." If someone could help me understand what this error means and how I can fix it, I would be highly appreciative.
Thank you
