box position for FlowTool


I am using the flowTool to get volume flow rate through an opening in between two chambers in a geometry where fluid passes from one chamber through that opening.

To get the accurate flowrate, should I place the box such that that opening falls somewhere in the middle of the box that encompass the opening coordinates? Or should I try to position the box such that the opening falls flush on any of the face of the box that is same size of the opening?


  • It is a bit difficult to comment on w/o any pictures, but could you perhaps do both and see the end result?

    Then you should have the insight needed to decide what is most suitable for your understanding of the physics.

    Kind regards
