In the sectional view of my fluid geometry, there are multiple regions separated from each other. I want to calculate average pressure values in each of those regions.
Example : Consider two pipes parallel to each other. The flow volumes through those pipes are also parallel. If we take a section plane across the pipes, two separate regions are formed in that plane.
Whenever I try to measure average pressure using pressure contour defined using my section plane, it shows the average pressure value of all the regions, not individual regions.
If I do the same thing in Autodesk CFD, I will get the average pressure values at each region of that section.
Like pressure at region 1= x bar, pressure at region 2 = y bar
Please help me find a way out.

When you create the plane, you can select which body to refer to. I think you have to make two planes, one for each domain.
