Re: amg solver
 
Murash,

You are using the amg solver. Although tech support will deny it, it requires a very robust mesh. I would bet that if you switch to CD, it would run. There are probably one of two mesh problems - cracks or centroids. Another problem cound be connectivity. Check for these three mesh errors and fix them and it will probably work.
