Check the mesh quality.

FINMES is an abbreviation of FINal MESsage.

It is possible that your calculation diverges. Then your time step is too large. More likely is that your BC's or model settings are wrong or unphysical. Please check these very carefully.........

I have met the same trouble.I have taken screenshot of the simulation.I feel the trendency are wrong.Can you help me ?Thank you!

Your simulation has diverged. Need it improve the numerical stability. Check the set up is correct, then use smaller timesteps, or a better intial condition. If you are desparate you can go to upwinding but accuracy will suffer.
