Volumic flow rate as boundary conndition

[Tsubasa]

Hello all,

I'm sorry maybe this is a little bit stupid question.

Let's say, when there are three inlet faces of the same shape, and I give a volumic flow rate 13 (m^3/s) in GUI to all three inlet faces.

In this case, each face has 13 (m^3/s) volumic flow rate, right?
It does not mean the total of the three faces is 13 (m^3/s), right?

Is my understand correctly?

Best regards,
Hamada

Hello,

The volumic flow rate is for a given inlet zone. So if all 3 faces are part of the same zone, the flow rate applies to the total.
If each face is part of a different zone, the flow rate applies 3 times.

So it all depends on how you choose to define boundary zones based on the mesh groups and geometry.

Best regards,

Yvan
