Spawise averaging within a cellSet
 

I need to conduct a span-wise average (Channel flow case) of a volScalarfield within a selected cellZone.

But I am not able to figure out how to reference a cellZone and code span-wise averaging.

I got a utility on this forum called 'postSpanwiseAverage'. It does everything I need, but it does that for the entire mesh,

Is there way to make 'postSpanwiseAverage' do the same averaging process for a particular cell zone and not the complete mesh.

The utility was posted by Marian Fuchs (http://www.cfd-online.com/Forums/ope...tml#post392279).

Can someone please help me
