Liquid surface artifacts

[beenyweenies]

Hi guys, my simulations are pretty much all liquids, and all happen at smaller scales (CG product shoots). Every time I run a sim with prefilled liquid, the surface devolves into a very noisy mess with visible artifacts. I'm familiar with tools like RealFlow where there's some benefit to running out a few seconds to allow the liquid to settle, but that doesn't help here. I've let it run for 10 seconds and still get the same result. Image attached shows what I'm seeing.

Is there some particular setting that would contribute to or mitigate this issue?

Hello,

Can you show us your settings?

I will have to use two posts to share my screenshots, limit of 5 per post. No foam or splash/mist.

From what I can see - your liquid is not that high res - it's only 4.6 million particles - what you can do is to increase your resolution a bit. The other thing you can do is under the Mesh options there is a checkbox "Use liquid particles for smoothing" - turn this on and play a bit with the "smoothing particle size" this should give you a smoother mesh.

Also, if the liquid looks like it's 'boiling', you might need to increase the Unit Scale from the Grid rollout in order to stabilize the simulation.

Thanks guys, I'll look into these options. I've been working with a scale of 1 because I'm doing tabletop-sized sims (splashes on cosmetic goods), and figured that would give a more realistic look. I'll push that to to 2 or 3 and see what happens.
