Dear all i am doing numerical simulation of francis turbine an d want to calculate the efficiency so for that i need to first calculate the total torque how to calculate the torque in CFX my rotation axis is z axis and if i want to select the hole runner domain in calculator about the z axis i am getting error "vertex point mismatch" please help me at waht location i can calculate the torque for turbine. i have 13 balde runner and i am doing my simulation by taking one blade passage.

hey i got it but i have now another problem i cut the passage between two blades like that i have one side suction surface of the blade and another side pressure (i can say one side half blade and another side half blade) and i don't have one single blade so it is possible for to calculate the torque with my case or i have to modify my geometry in cad software and do meshing and simulation again.

In the calculator, select the blade part to get the torque, also select the hub and shroud incase you have them included. Can you confirm this is a steady state run with a single passage?

my problem is i don't have part name blade,i have the passage one side half blade surface and another side half (pressure surface and suction side surface)so in calculator i am able to get torque for only one surface either suction or pressure surface
