So I can't use patchAverage since my patch is internal.
I then tried the integrate variables filter over my internal patch by using the slice filter. However, my results didn't seem right. Am I doing something wrong?

Also how does the user know whether the integrated velocity is Ux, Uy or Uz?

I'm trying to find the area-averaged Uy.

I had a similar problem (integrate a variable over an internal plane) and managed to do so. Please refer to this post and see if it helps: http://www.cfd-online.com/Forums/ope...tml#post581774
