Hi, everyone. I'm setting a "prsssure far field" boundary condition. But, when I start to initialize it, the Flunent main window always inform me: Error: divergence detected in AMG solver: pressure correction Error Object: () absolute pressure limited to 0.000000e+00 in 1241 cells on zone 1 I don't know what had happened. Who can give me a hand? Thanks a lot!

You have to change the pressure limits..Increase It higher than the far field pressure..Good Luck

Yes, I've tried it. But it is the same result,if only I use ideal gas. Well, if I use another fluid, everything will be ok. I have to use ideal gas, however, so I can employ "pressure far field". Really, it's still not clear for me. Thanks a lot!

Pressure far field is always used with compressible flow where you must consider the flow as ideal..I may be able to help if you can describe the problem you are intending to solve..GOOD LUCK...
