Kappa Epsilon Turbulence model reaction forces

I am modeling an airfoil using the kappa-epsilon turbulence model. In the post-processing I want to extract the lift and drag forces to calculate the lift/drag coefficients. I had done this before using the Spalart-Allmaras model by following the "Flow around a Cylinder" example and it worked properly. However, when I tried to do the same thing with the k-? model the reacf() operator is zero. I searched the forum and found another thread with the same problem. In that case, the operator “T_x” was used to obtain the force components. However, I am working in version 4.1.0.88 and that command does not appear on the User’s Guide or in the “Computing Accurate Fluxes” section. Nevertheless, I tried that command on my model it did not work. Is there any command that I missed that will allow me to obtain the reaction forces in the kappa-epsilon turbulence model?
Thank you!
