I encountered the following simulation error:
I tried reducing the step size in the solver but it doesn't work. How should I fix this?

It turns out that 3.5 seconds also yields a non-finite result. I changed the stop time to 2.3 seconds, and here is what happened:

Does this mean I have to tune my PID gains now?

I am a little confused, in that your original post the error message had a singularity about 1.88 seconds
Sorry, I have never looked at airfoils at all.

Are you using a fixed time step in your simulation settings? if yes, then try setting it to variable time step and see if it works.
