Good day, 

I am trying to model the flow of water that is pumped out of a tank by a submersible pump through a direct coupled discharge pipe.  

When trying to generate the surface mesh, Fluent splits the discharge pipe, and the fluid zone in the pipe, into three domains that are dead zones. I am not sure why it does this. Could you kindly advise on its cause and solution?
