Venturi: velocity & pressure simulation

      Hello, I was trying to create a fluid simulation for a venturi based on

      ">The Venutri YouTube tutroial   to achieve the velocity & pressure graphs. However, seems like there's a big difference in the results in terms of the velocity , pressure, pressure vectors etc.

       

      I believed I have followed every step in the tutorial. Any  possible causes to the discrepency? thanks

    Assuming you have the same density model as the tutorial (I can't access for some reason) check domain scale. What you've picked up is an asymmetry in the flow and that's the caused the jet to attach to the side of the domain: that's a real result, and you may want to read up on the Coanda Effect.
