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... Hrv

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! Antoine |
