Next step:

I defined a sampleDict with a plane exactly like in the function object and made samples of U, magU, p.
Integrating the sampled surfaces in paraView leads me to 12 m/s, so different...

I never actually did any kind of wiki entry but I will try to find time at the weekend!

Okay:
I did a sum of the area as well and compared it to paraView: 99.71% identical size.

I triple...

Big thanks,

with this code I can observe the mag(U) value on a self defined plane for each time step!
Wonderful!

This was very helpful. Unluckily the behaviour is the same like the other...

Hey,

Great thanks for your quick reply!
I checked the magU field, slicing and integrating it in a paraView leads to 12.05 m/s, so the field data actually seems to be ok!

The problem seems to...

Hey,

I am sorry to bring this up again, but I experience problems with the described way of calculating the average mag(U) over a plane.

I have a simple pipe (flow is 12m/s with air, laminar,...
