Sorry but the article is PR department nonsens. Even in the paper adstract:

Meshes that conform well to changing boundaries and that focus computation in the visually important parts of the domain can be generated quickly and reliably using existing techniques.

There is no new â€śfluidâ€ť equations and this is just another approximation.

For the record here are some other points:

First of all we have been doing fluid dynamics with all the accuracy we can get since computers were computers. Most donâ€™t care about apperance they care if the plane will fly of not. This means codes that conserve relavent properties.

Secondly *any* computer must *approximate* the fliud (there are 1 billion cubic millimeters in a square meter! you run out of ram). But thats OK it can still be accurate.

Thridly computer graphics does not need accuracy but good looks. The fluid pluigin in Mayer is not even close to accurate. It dumps all compressive flows so that there is only vorticity left. In fact the blender fluids is probably one of the closest to the true NS equations out there.

Iâ€™m reading the paper now. (I should be writing my own paper)

Delt0r: Just out of curiousity, can blenderâ€™s fluid system handle multiple liquids such as oil/water?

No not at this stage. But nt keeps adding things and his orginal work included air/water type simulations.

Oh i read the paper. Its is just a â€śmovingâ€ť mesh method where the entire domain is remeshed each time step. Odd aproach really, the animations look cool tho. But they donâ€™t claim to have new fluid equations in the paper. So Perhaps the PR was the reporter putting there spin on things.

The smoke looks cool but the liquifying character doesnâ€™t look like anything that Blender canâ€™t do with a little more work by N_T with his current method.

It may be just another method of doing fluids overall.

I think you read the wrong paper, this article is about â€śStable, Circulation-Preserving, Simplicial Fluidsâ€ť:

I find it actually quite an elegant method they propose, using the vorticity equations neatly put into discrete differential geometry. Of course it doesnâ€™t allow new things really, but simply a faster way to do the same thing, like most graphics papers. This paper was already in the siggraph 2005 course notes, but only now published.

Yes you mite be right, I just followed all the links and only one lead to any articles.

However as far as fluid dynamics is concerened Its not new. They even say that in the introduction. Its new for visual fliud dynamics. My points above still hold. there is no new fluid equations, its still approxamate etc.

However it does look interesting.
