CFD-Post axial pump torque

An axial pump problem was solved (inlet, impeller-archimeds screw, outlet; BC in: total pressure, BC out: mass flow). The resulting pressure rise is comparable with experimental values. Now I need to calculate reactive moment (torque) on the impeller from fluid for further calculation of efficiency of the pump. I tried to use "function calculator"->torque, then selected blade's side surfaces (or hub's cylinder, or shoud's cylinder, etc.) but the result is always zero about all axes. What am I doing wrong? How to calculate reactive impeller moment correclty?
edit1: no "turbo" macros were used in pre-processor, so can't use them in cfd-post
Thanks in advance.
