Afternoon specialist. I have some troubles in CFX using. My CFX simulation result is so strange, From pic1 you can see result maybe convergence, but at the end of this simulation the colour line convergence separately. in pic2 the monitor showed the results were stable. So I try to increase velocity 6 times. pic3 and pic4 showed the simulation situation was better. I would like to know the reason should be mesh cell was too large I guess. right? Can I use this result directly?
