Hello~ all,

I would like to get the reconable drag and lift coefficient.

First of all, if we wanna get them, we must set reference values in fluent.

Simulation model’s shape look like bullet. And I wanna know coefficient due to Mach number and angle of attack.

So, I did set like these.

area : Projected area(like circle)
length : bullet’s length

Then I can approach the coefficient in solution>Monitors.

But Area which I set in reference values is projected area(from flow direction).

So drag coefficient is ok. But could I get resonable lift coefficient from that settings?

Or, If I wanna get resonable lift coefficient, then I did set another direction’s projected area(like rectangular shape).

Best regards,
