Hello,

For a project, I need to study the impact of a pressure wave of a tornado on the blades of a fan. So, I modeled a ventilation duct with a fan inside.
I would like to know the torque of the fan so I go to:

Report->Force->Moment-axis-of-rotation and I get a moment but the value is wrong ( 0.0005 m.s ). Maybe because I use Moving Reference Frame, I set a velocity to the fan so there is no change whan I apply a pressure a the entry of the duct.

I need to know if the pressure of the tornado sets overspeed the fan.

Is there a specific configuration to do?

Thank you very much
