Hello,

in CFD POST, I cant evaluate torque and force on a few faces, I receive error:

ERROR:
Flow data - vertex count mismatch

other evaluation works on these faces, such as area average pressure, temperature etc.

??????????

I have never seen that error before. There must be something very strange about the face you are doing this to.

Yes it is very strange. I tried to evaluate Area Integral of Pressure on given surface in X direction as well as Wall shear and it works! Obviously I would be able to evaluate the forces on the basis of these surface integrals.
But I need to evaluate torque as well. However to create my own expression to evaluate torque to an axis of my local coordinate system seems to be a difficult task.
