      Hello,
      Below photos shows my welding nozzle geomerty.

      Inlet - green section.

      My desire state is that it exits at 9 little holes into air fluid domain, and then go to the end and bounce.

      How to approach this? Can outlet also be a wall that bounces back gas? Where should i define outlet?

        

      Right now i have outlet defined at the end, but it seems to not bounce/spread.

      When i tried making this 9 holes as outlet, fluent doesn't show Outlet section.

       

      Best regards,

      Alex

      Hello, 

      is the box a Fluid domain? If so, the whole should be set to internal.
