Error: Non-linear solver did not converge

Hello,

First of all, I am a new COMSOL user and very unexperienced in this software.

I am working on the beam rotor and hydrodynamic bearing physics to simulate a shaft and two foil air bearing to see the whirling of the shaft during rotation. Every parameter had been set-up and during computation, the solver takes more than a day to solve thus I cancel the computation midway. Then, it shows that the non linear solver did not converge. Can anyone help me why is this happened and what should I do to solve this problem?

I am unable to share the mph file here due to the size limit but I am willing to share the file through email for more references.

Thank you and appreciate your attention to this matter.
