Hi,

I lately come across an alternative method of solving fluid problems. (instead NS-equations) These methods are called lattice methods an calculate the paths of descrete particles on molecular scale.

Could someone give a comment on that technique compared to the traditional way by solving the Navier-Stokes equations ?

Regards,

I have come across this method recently as well. It is based on Lattice-Boltzmann theory for gases i think. the example I have seen worked reasonably well, but only in the simplest configuration...

A quick search on the web will give you the answer. I did so, and I find :

which seems to give a good introduction to the method.

Moreover, Powerflow from exa corp (www.exa.com) use this method.
