Hi sivan , yes i have rvo2 2d and rvo 3d 2 but if i dive inro rvo i would have to request permission from the university of north carolina , perhaps i might just get it who knows...

I also have jsbsim for flight dynamics simulation but okay thats a project im net getting into now..
The main reason i went for opensteer first is its license ..

Yes they say that they cant guarantee it being functionaly stable but i have not seen any demo that proves it not to be good enough for small uses..although yes i understand what you are getting at.
