I would usually use cloth with just enough gravity to have an effect, depends
on the weight of the fabric though, and hand animate a wind effector randomly
in intensity as well as it's direction down the flag, should work fine, but use
a fairly dense mesh for smoother results...
or try Syflex :)
Hope it helps,

Subject: Cloth sim flag ripples?
I am working on creating a flag being pulled through the air, looking for a
nice rippling slowmotion style effect. I seem to be unable to get satisfactory
result with noise, and setting up complex systems of fans prove difficult to
control.
Noise seems to affect the flag in a non turbulent random way like a noise
field deforming the cloth rather than rippling it. I really wonder why we can't
use turbulence forces on cloth - it seems so obvious to get realistic motion
from that.
Anybody care to share a tip or two - or should I go the good old way of hand
animating it with waves and all that?
Best Regards
