Depth-averaged quantities in ParaView (interFOAM simulation)

Hi,

How can one generate maps of depth-averaged velocity in ParaView.
I am post-processing a VOF simulation (air/water) done in interFOAM.
What I am looking for is a 2D map of depth-averaged quantities such as velocity in the entire domain. Just integrating/averaging over a vertical line won’t work (I need this done in the entire domain).

Thanks

ProgrammableFilter should be able to do this.

you will have to implement the algorithm in Python though.

Thanks for your response.
Could you please provide some more info (e.g. sample code)?
That will be greatly helpful.
Thanks.
