Average Temperature in a Subdomain

I'm running a multiphysics simulation in COMSOL (3.5a), using Conduction and Convection and Darcy's Law. There are three subdomains of interest to me, and I am trying to obtain the average temperature in each, as well as in all 3. However, the results do not make sense.
To obtain the average temperature, I measure the volume using the geometric properties button (agree with hand calculations), then select the subdomain, and under 'post processing', select 'Subdomain Integration'. The expression I use is 'T/vol' where 'vol' is the volume of the subdomain in question. These results do not make sense - the subdomain that ought to be the 'hottest' both logically and based on the temperature slices is in fact the coldest based on this calculation method.
Anyone else have any problems with this method or see some misbehavior?
Thanks,
Nick
