Hi dodun,
I do not understand whether the water is in the pipe, the box, or both. If there are two different fluids, what is the other one?
If water is inside the pipe and box, then Simulation Multiphysics can solve it. (You may need to use unsteady because a steady state solution does not exist very many times due to the nonlinear nature of fluid.)
If there are two different fluids inside the pipe and inside the box, you will need to get an answer from someone at Autodesk. It may be possible with the coupled analysis, and there may be other alternatives, but I do not know what methods support different fluids.
In my particular situation, the fluid will only be flowing through the pipe. Imagine the box to be a solid metal box with a hole in the middle enough for the pipe/tube to fit through to allow fluid to flow through the tube. A better visual would be like putting a straw through a large die (dice). Thank you
