asking for Boundary condition in FLUENT
 
hi all...

I want to ask about boundary condition in Fluent...
I have run a case about fluid flow around pipe...
I followed the instructions from one of the training modules from Fluent.
when I set the boundary conditions on the inflow I can set the velocity at that location but when I want to set the outflow boundary conditions in this part I experienced difficulties since this section does not provide a column for velocity. how do I set up for this outflow boundary conditions ?
how about for the bottom and upper layer boundary condition?
what kind of boundary condition case do the Fluent run?
is it Dirichlet boundary condition or Neumann boundary condition or Mixed boundary condition...?


Regards
Destry
