in mixing tank for example near the impeller energy dissipation rate is very high .i want to have volume this place but this volume is non uniform .i want to have flow rate and volume ,and mass wiethed average of dissipation rate of this place.i went to iso-clip and chose the range of high dissipation rate and created the surface and then went to integral surface but i think i shuold have this place in integral volume\but this ragion didnt come to the integral volume.how i shoud have information (such as flow rate )about non uniform volume in fluent.plz help me.thx

What was wrong with a surface integral for a mass flow rate? It should work regardless of the composition of species flowing through.

As for volume integral and the region not showing up, that sounds like you may have a mistake in your geometry generation where you're not closing off that region as its own entity correctly, or maybe you specified the wrong BC type for it in Fluent, e.g. interior...
