Position of the center of aerodynamic forces

Hello,

I have a 30 meters long frame that resemble the chassis of a plane.

I simulated the effort due to a 100 km/h wind and got my results. I used variable pressure on my tubes and I did my study only on the front part for mesh timing purpose.

Then, I checked the reaction forces and moments list but I also need to find the exact point where that force and moment is going to be.

I have attached a print screen of this. I am perplexed on the fact that the biggest torque is around the X-axis when it should be around the Y-axis.

I have been looking for days, so I don't know if I am being very clear. If you think you can help me and need more details, don't hesitate to ask.

Thanks,

Best regards.

Seb.
