Hi,

I use both weightedAreaAverage and AreaAverage to track my tracer at the outlet of a pipe. I have found some threads here ( Area Weighted Average) that says, that weightedAreaAverage is a better approach to track a tracer. Can someone explaing me why, where does this approach come from?

Also I use both methods, there is simply no difference in the values, but I think there should. I have a parabolic velocity profile in the pipe.

Can someone give me more insight in this? I have tried to find the source Code to find how the weighting is exactly done in OF 4.1, but I couldn't find it.

Best Regards,

Gesetzt
