Hi, i'm using cfx to simulate an airflow with a wing that I dont know its properties. I need to know where the forces are acting ( their location on the geometry) to calculate the moments and etc.

There is a way to do that?

I have a guess that when the post-cfx calculate the force on direction Z (for example) this means that is the force applied on the origin of my coordinates. Is this correct? Or there is another way to know where the forces are applied?

Thank you in advance for your help,

Michel.

The forces are over the surface in consideration integrated pressure and viscous stress (if not in-viscid) quantity. If on openings then mass flow force is added. so the force in Z (force_z) will give you the component of force in z direction.

Best regards,
