Dear All, I am performing a wells turbine calculations and I want to calculate the torque. My solution converges well but the problem is with the moment report. my torque is very low (only due to pressure not viscous force). I tried different mesh topologies and all give me almost the same number (which is very low compared to experiments). is their any adjustment that must be made in fluent before starting the calculations!!!! is it a must that the solid rotor mesh located inside the fluid mesh? can someone please give us detailed instructions about torque calculations??
