Error: divergence detected in AMG solver: pressure correction what does this error imply and how to correct it.

Re: divergence detected in AMG solver:
 

Try to reduce Pressure under-relaxation factor to 0.2 (Solve->Controls->Solution).

P.S. If you have this error using the drag factor you implemented using UDF, you should also check it's implementation.
