Candidate for integration: corrected particle fluids patch

Hi all 🙂

Thanks to Jahka review and advices I have corrected the particle fluids patch and have simplified it for better integration. Also I have discovered and solved an important bug in the multi-fluids interaction that caused strange behaviors in fluids.

here you will find the new patch:

and here a new test blend:

http://www.pasteall.org/blend/2223

The short list of changes are:

– Important multifluids bugfix.

– Better defaults and parameter naming.

Cleaner patch.

I have temporarily removed the particle color and temperature visualization since they are targeted for future design in Jahka framework, but once committed the code will be easy to add back.

I will soon upload a pdf with all the features of particle fluids.

    Sweet! Tried it today for the first time (yay! I managed to apply a patch : )

    I would try it for hours if I had time. But those few minutes amazed me. About the surfacing thing.. did I miss it or is it a wip apart from this patch?

    Saludos!

    collision is too simple and bad… (bouncing fluid…..)
    the solver is very unstable with many particles
    try 20000 particles… does not work.

    It seems that a recent change in the trunk makes this not work. The partials seem to explode after a few of them collide with a surface. The chased simulation looks fine but if i change anything it goes crazy. I’m sure it is nothing big. I will try to find the revision that caused the problem.

    Seems that something has changed in the latest revision, I will see what happen. And about bouncing fluids, take into account that you have to play with all the parameters, viscosity and particle damping increase stability as fractional timesteps do.

    A tutorial is urgent because people could report as a bug unknown functionality 🙂

    cheers
