hello,
what do you exactly want to modeled? navier stokes equation are very complex and can be used to modeled lots of things like the acoustik of an organ or the whole earth atmosphere...
well i thought of something like realtime video controlled fluid emitters for an installation (bodymovements distorting virtual atmosphere (like hot steam)). i thought of realising this with particles but allways got somehow "to rough" grains.
I think implementing navier stokes equations in gem is a big work, and to make it work in real time is quite impossible : profesional software like fluent does not work in real time, even for small system.
i thought that to.... it was just a question of "somehow and maybe"
in some very special case, the navier stokes equation got an explicit solution (most of the case, it's highly chaotic). in that specific case, it's not so hard to draw the solution in real time with gem. there is a try in the pmpd exemples : exemple 19, 20 and 21 are a modelisation of a specific solution of navier stokes equation in a 2D field.
yes i think they could be quiet handy-- thanks
(to try them, you have to get the pmpd lib : on the cvs or at http://drpichon.free.fr/pmpd)
hope that help, cyrille

hi as i am no programmer i only can fairly estimate how hard it is to implement navier stokes equation in gem objects. has anyone thought of something similar yet. i think such object could really give very nice control data. lg and regards wolfgang schwarzenbrunner
