Default Volume average of a scalar?

mecarlg is on a distinguished road

Can anybody help me with this please? I have a flow field with one volume and I want to calculate the volume averaged scalar concentration in a sub-volume.

It is easy to do for the whole volume (report->volume integrals) but how do you create a sub-volume not part of the mesh file? You can only create points, lines and surfaces in the Fluent GUI, any tricks for creating a volume?

I have released the scalar from a sub-volume using a UDF but I'm having difficulty calculating the scalar concentration in other sub-volumes. I do have other models with the volumes decomposed already but its not very efficient if you need to know a volume average somewhere else.

Any help is much appreciated.
