Flip solver sheet preservation/smorganic/sheeter effect

[EL_CISNE_POST]

Hi, I have been working with the nightly build for a few months and I'm pretty happy with the results I had so far, but I would like to be able to push it further but I honestly don't know the limits of this new flip solver. I work mostly at advertising so, in most of the cases, I have to create splashes and liquids, and I'm at this moment facing a real deal with some milk simulations in slow motion that my client wants (Here are the links http://www.shutterstock.com/es/video...piA:1:86/photo

I have done some nice tests (I can't share videos here that I haven't uploaded first) but the reference they gave me are quite natural and at this moment I cannot achieve that kind of beautiful liquid sheets as the reference. I have seen that other softwares that use flip solver have developed some tools to achieve this kind of result as the RF Q solver http://cgpress.org/archives/q-solver...available.html and https://vimeo.com/12992186
The liquid tends to break apart pretty easy and it doesnt preserve this sheets.
I'm wondering if you can help me, with any tip or letting me know that this cannot be achieved with phoenifd flip solver.
Thanks!

Hi, Phoenix has no special tools for this, you can try to use some surface tension (0.2-0.5) and to increase the spf or better to decrease the gravity (if slow motion is required)

Thanks for your answer Ivaylo. I have done some test these days and I was able to achieve this kind of results that are pretty nice but for the slow motion test I'm running, it is not giving me the look I need (actually I had to report an issue about a flickering on the mesh, event using the particle smooth, support told me they sent it to developers because they had tested the scene [#761519]). Do you think that in the future this kind of options will be contemplated?
Thanks again

looking good.

For "_scene - test_07.avi", the end part of the animation, the liquid starts to split apart. In realflow, they have sheeter daemon to fill that gap.
In real life production, take this video done by Trizz for example, some shots they use static liquid mesh + FFD modifier for super slow motion

you could try snapshot one of your PHX simulation liquid mesh, use that and add FFD OR Mopher to cheat the effect

Hi Hammer, thanks for your answer. That's a pretty good approach and a really nice example. The problem I have is that I'm not going to have something quite like that, first because is really really slow the way they are using it (and I guess that's why it works), but in my case I need to do something like this http://www.shutterstock.com/es/video...0ZA:1:96/photo that is slow motion but is a full sequence, and the splashes need to look better, with thick edges and no holes on the liquid sheet. I'm still doing some test but it seems it cannot be done with phoenix
Thanks for the help

can you share the settings you are experimenting with?

[EL_CISNE_POST]

Sure, I'm sharing one of the scenes. I have found that some of the times is better to rise the SPF and use no surface tension, because it seems that the surface tension tends to brake apart the sheets faster. The good think about the surface tension is that it tries to keep the thickness on the edges.
Also, one thing that I would like you to notice on the scene, is that most of the drops are equally in size and that gives me a very unnatural look, I honestly don't know why it is happening, because my settings are quite high.
Thanks!

PD: I didn't know if that's the scene you wanted to know the settings... if you want the other one (the explosion) please let me know, is just that I don't have that one at the office.

Best
