Hello dear everyone, thank you for your help as always.
I'm not good at English or programming, so I'm sorry that I always seem to make basic mistakes.



To briefly explain the shape I want to experiment with, two inlets and two outlets exist simultaneously in one fluid flow.
Here, there is an inlet called A and an inlet called B, and an outlet called A' and an outlet called B'.

Here, it is ideal that all of the flow coming in from A goes out to A', and the flow going out of B and going out to B' will interfere with this flow.

I have two questions here.

1. If two inlets are involved in the flow out of both outlet, is there a way to quantitatively check what percentage of the flow from specific outlet is occupied by the flow rate from each inlet?
From this, we want to see how ideal the flow was.


2. When the flow of the two inlets and the two outlets has a slightly complicated shape, is it possible to calculate the degree of flow that enters from the inlet but does not go out through the outlet and is isolated in the pipe over time?



The analysis is running at both steady and transient and the fluid is water. Thank you for your help as always.
