2 or more GGIs with non concurrent axis?
 
Hi all,

a very short, hopefully not so stupid question:

Is it possible to simulate 2 or more GGI pairs, that do NOT have the same axis and angular velocity?

If yes, how to define them in my dynamicMeshDict?

Thanks,
Antoine

There's no problem with the GGI: it doe not know anything about axes or motion.

I guess what you need is a multi-rotor dynamic mesh class - I think I've got something lying about but it hasn't been used for a while...

That's what i thought about GGI, that it should be no problem for it, having different axis, origin and angular velocity. Though i could not find any piece of info on that...

I would be of course interested in seeing how your multi-rotor routine looks like, if you can find it again. Would be great!
