How can I do?
 

Now I use CFX5.6 for design and analysis centrifugal flow fan. I have a problem when I run CFX5.6. It show me that "fatal overflow". How can I put in the boundary condition?

Hi Smith,

There are many factors which can lead to a fatal overflow - I assume in the linear solver. Generally it means to solution has diverged rapidly. Have a look the posting at:
