I keep getting this error but sometimes it's just a warning so the solution may or may no converge. What factor let the solution converge?

Thanks

Do you get any other errors/warnings in this analysis ? How does your definition of rotary inertia look like ? Didn't you specify negative values ? This may be the reason.
