Splashes and foam: what difference between?

Hi there! Tell me please, what difference between splashes and foam? Because PhoenixFD splashes are looks like bubbles and is it real to make them as RealFlow splashes - like a paint ?
I think that if PhFD splashes do smaller - it will be like PhFD foam.

For example, what I mean to do:


Could PhoenixFD do this nice splashes ?

Thank you.

the phoenix splashes are for big scale epic scenes, not for cases like this one. you need pure liquid simulation without any splash or foam enabled.
i think to get results near to the ones in the images you have to use the particle based solver, that we are implementing right now. it’s still not open for nightly build test, but it will be soon.
i did a fast test, see the image.

It is very interesting in perspective. Thank you. But unfortunately I can not open the image :frowning:

Do you mind saying what kind of soon you’re aiming for? weeks, or months?

Verbmeister - phoenix can do those kinds of things. the splashes in phoenix is not what you think of as a real world splash - it’s for giving a better result when viewed from a distance.

I’ve been working on this with phoenix, which is probably in line with what you want to do:
(this is much thicker than water, I have the viscosity turned up)

Neilg It seems to me is very interesting! Could you please not only show results, but open custom preferences ? Thx :wink:

It’s just 3 emitters, viscosity .2, time scale .1, pretty much no gravity, and a phx turbulence object to whip it around and disturb the surfaces. everything else is default, the only tweaking I did was to the turbulence settings.

hopefully in one month, but don’t expect full support from the beginning, there is no foam, no adaptive grid, no resimulation, no restore.

I’m not, i’m just always excited to see what you guys have been cooking up :slight_smile:

Dear Neilg, I just try to do some “splashes” with your recomended prefs, but I did not recieve the same result. Please, how did you do thin translucent surface without gaps ?
If geometry emmitter is, for example, has width above 1,5 cm - there is fat surface mesh, but if below - there are gaps in surface mesh (

Could you please upload image, for example, to iceimg.com ?

here is it

That sounds like your grid settings are too large. i’m also rendering with SSS.

Thanks, Ivaylo, it is too smoth without real splashes, isn’t it?
Thanks Neilg

Trying smth like this:

Particle based solver by Chaosgroup ROCKS!!! Great news to hear! Can’t wait to try it! With you guys I’m sure it will be the best implementation with the best support once officially released!

more splashes:

not sure what you mean, perhaps the droplets in the air? don’t carry about them, they are easily achievable.
let me explain about the most important (in my opinion) detail in your goal. you are trying to create a kind of splash that has droplets and some thin sheets of liquid. exactly such kind of simulations are pushing us to add particle based solver in phoenix. the problem with the grid is that when the sheets become thinner and thinner they start to break at some point. and in the grid simulation they break along the axes, getting very unnatural appearance. to get rid of this you need huge grid resolution, that leads to very long simulation times.that’s why i mentioned the particle based solver, despite the fact that is still not accessible for the users. it’s not a secret or such, we just try to prevent the infinite bug reports that will be caused if we open it. so, if you are a customer, and if you really need this, we can give you a build to make experiments.

Dear Ivaylo, Thank you for your comments and explanation. I just try your product as potential customer with Phoenix demo. Yes, I need it for those splash simulations and now select wich of products will be comfortable to me: Phoenix FD (inside 3dsMAX that very usefull in a singe environment), or Realflow (that has splashes for the default, but another programm).

well, as i said our particle solver is still under construction, but we allow the customers to use newly developed features, so keep this in mind when you decide.

Greetings Ivaylo,
I am a customer, and would like very much to try your particle solver for testing. I have used Glu3d before and switched to Phoenix with great success.
Now I need to simulate coarse and fine water spray from an industrial rotary nozzle under pressure, over 100 gallons per minute. Not very practical with grid solution.
Hoping you will consider to let me try it.
Thanks,
Ron Porter
