Build the plane in CFD POST
 

Attachment 15378

Hello everyone, Above picture is my geometry. I've already finished my simulation. Next is to look at the result in CFD post. As you see I have multiple tube, I created the xy plane and it cut all tubes cross secton area but I needed only one tube on plane to calculate average pressure.

How can I creat the plane that cut only on tube ? or how can I size the plane

Thank you guys

Use the point normal method and circular plane bounds (slightly larger than the tube diameter). Ensure the normal is in the direction of the flow.

The CAD model can easily provide the points or even a line along the center if the tube that you can use.

Thank you very much,
