Hi all,

This is jsut a quick question. I hope that theres a Yes/No answer, and If its yes then pointing me to the right terminology to look for in help/other threads should be enough!

Basically, I am looking to simulate a gliding bird. But the specifics of the simulation isnt all that important... My qestion is, can you with CFX, set say airspeed and a desired lift force and have angle of attack parametric so that it settles on a value that satisfies both conditions above?

I am simulating something for which I have no way of knowing the exact angle of attack and airspeed combination to achieve a desired lift force.

I understand that this would require an adaptive mesh.

I have another project running simultaneously to this one in which I am plotting Cl, Cd and Cm vs Angle of attack for an aircraft at constant Reynolds numbers. And I wouldn't say Im a beginner with CFD/CFX (far from expert, very far) but I've been trying to think about how to plot a glide polar which is done at 1G (const Lift force), and I dont really want to trial and error my way through setting an airspeed and varying angle of attack to achieve 1G over a range of airspeeds.

Using thin airfoil theory to approximate Cl as = 2pi * alpha crossed my mind, but I thought I'd see if it is possible to set it up within the simulation so that this isn't needed any more than to perhaps estimate where it may be.

Sorry if this is an obvious or stupid question, never know perhaps I'd realise Im thinking about this the wrong way around if I leave it for a couple days, but I've been racking my brain and thought I'd throw it out there.

Thanks
