Calculation gets stuck

Hello,

I analyze flow in bearing, multiphase flow - oil and air. This analysis is running and suddenly gets stuck, in the middle of an iteration, without any obvious warning or evidence of divergence.
It occurs on different computers, also in cluster, so it should be problem of the analysis and not the hardware problem. For different boundary conditions it suddenly diverges, but for other boundary condition it just gets stuck in the middle of an iteration. Is this stucking caused by divergence?

Please attach your output file. That will show where it is getting stuck.
