Anyone produced some interesting fire sims with 2011 yet? Would love to see some results, any fluids for the matter.

Cheers.

I just posted an explosion I did in 2011 in a different thread.

Any examples of using the new features of fluids like the dynamic noise, forward advection, self attraction and repulsion etc etc would be great these I believe will help to make awesome fire and explosions.

I used forward avection on the explosion and substeps. It really helped keep the fire and smoke in a column.
The feature that is really cool is the Auto Resize. It makes a huge difference in simulation time. You can really fine tune stuff a lot faster. Also, instead of using a field I used the self force feature to give the explosion its initial burst.

I did experiment with the new noise parameters but for this explosion it just came across as popping.

Can you increase the self repulsion by ten and see what you get i the initial blast? Maybe key it off and key on self attract to bring it back in again, just an idea to play with. Perhaps the noise attribute is better suited for fire?

Anyway like you say the auto resize is about the best thing to happen with fluids, its brought the fun back in it for me.

[Edit] I just checked out some of the notes - I mean to say lower the eqilibrium threshold of self force and maybe just on the temp grid. Only if you have time Todd, dont mean to be pushy :)

I have played with increasing/decrease the forces. Its kinda cool you can blow the fluid apart pretty quickly. Might work really well for something like a paint ball splatter mixed with some tension. Although I did start with self attraction, it increase my sim time without contributing to the final effect, but again I wasn't really trying to make the self attraction do anything. I did find setting the equilibrium to zero causes the fluid to explode immediately. I haven't tried reforming it again though.... based on the other settings it dissipates before being able to reform.

I made this too, as I was testing stuff. Its kinda like a small firecracker.

Im liking the fact that it is saving time rather than having to set up a field and tweaking its magnitude to get the right balance and feel.

So fast simulation on this release.

Pretty good for a newbie ytsejam1976 ;) If I got that on my first try Id be pretty happy with myself too.
