[@KelVFX]

Thanks so much for this, also thanks to Don Draper for doing the voice over.

[@mtscott44]

Thanks for putting that together dude, much appreciated.

[@DriesduPreez]

Excellent reference material here, thank you

[@aleksdrid4725]

Thank you for putting your time and effort to make that vid ! which actually flip fluids team supposed to make 😁

[@grzegorzabedzki3466]

Very good video! Thank you so much for making it. Definitely it saves me a loooot of time testing things.

[@theCreativeSav]

Thanks for this man. Very helpful!

[@dariobirindelli4338]

Thank you so much for the work steeve

[@PrinceWesterburg]

Strangely hypnotising! I'm running it on an 8-core, 16-thread E5-2680 Xeon and it seemed to use around 49% of the CPU time in bursts but I just got the April update with APIC and that uses less, around 39% CPU time at peek. Imagine if they made this GPU based!

[@AroundTheHouseShow]

Doing some viscosity tests tomorrow. This was very informative. Thanks for all the time and effort

[@semillerimages]

Hope it helps! It's kind of outdated now :)

[@zergidrom4572]

Damn, this would be epic informative for those, who want to pick needed liquid quality without testing it over 93641624 days :D

[@semillerimages]

Thanks!

[@s2mann]

This is extremely informative Steve. Thank you!

[@semillerimages]

Glad it it for you :) You're welcome!

[@armiks22]

This is most helpful, really, thank you. I've used this guide for 3 animations already.

[@semillerimages]

Awesome! So glad I could be of help!

Hi. Can you please tell how to decrease the fluid velocity during the process??

[@f4ust85]

You saved me a lot of time sir, thank you.

[@milansvancara]

Thank you, very helpful work sir!

[@violentpixelation5486]

Much appreciated. Thanks alot for the effort.

[@lz4090]

thank you for doing these tests and comparisons.

[@TheNemoff]

Hi, excellent video i have a doubt, how I can make the inflow object decrease the emission until stop? thanks

[@semillerimages]

Thanks! I do not know what your question means, sorry.

[@terryd8692]

I get the impression that there are more settings than you know what to do with. Resolution has a bit impact but I guess the size of your domain/object plays a big part too. A flow of water in a shotglass will act differently to a scaled up version of flow into a bucket, or larger still into a pool. It'd be useful if there was a simple 'water' preset as this is what most people would use.

[@semillerimages]

yep!

[@Ahivo]

you did put lots of hours on this video. thanks this is amazing

[@semillerimages]

Thanks! This is pretty old now, so things might be different with the newer version of the software

[@alexs6986]

This is amazingly helpful. Good work!

[@semillerimages]

Glad it was helpful for you :)

[@wtf.scaryking]

thx ...very helpfull

[@adictivedesign]

Hey, where exactly is the Smoothing Factor/ Smoothing Repeat setting? In the actuall version of Blender/ the Plugin i cant find it anywhere

[@semillerimages]

No idea. Haven't used the plugin since around the time I made this video... which was four years ago.

[@rdscreations3116]

Life saving video. Thankyou!!!

[@semillerimages]

Glad it helped!

[@pjwarez]

Sorry if I missed it, but I didn't see what size you had your objects at? I know in earlier versions of Blender, the size of your objects mattered quite a bit! What is the size of the Glass and Domain? Several inches? meters?

[@semillerimages]

The glass is 3 meters tall in the blender dimensions info box

[@semillerimages]

The domain is 4mx4mx8m

[@pjwarez]

@@semillerimages Thanks!

[@Leukick]

Very, very good work

[@ShindlerReal]

Is this before mantaflow? I'm not sure I have those settings.

[@sipsaoishiso]

How come surface tension and sheeting adjustments show us such a random baking time?

[@semillerimages]

Honestly, I simply don't know why. I didn't do 3 runs and average them because it was taking so much time already.

[@gokul8002]

sir can you help me i created a basic scene like a domain and then I created a cylinder to create a pipe so I deleted on side face from where the water would come .. and I put a sphere inside the cylinder so as their is no option for planer object so I added a solidify in the cylinder to make a solid then I applied the solidify so the water is just dropping down from the cylinder instead of coming out of the pipe

[@arehman7151]

Great comparison. I am trying to make one but the fluid spill out from bottom & side of the glass, I have made the glass obstacle. Can you help me to make a one like you did? Regards

[@semillerimages]

Probably your glass mesh needs to be thicker and more dense in terms of its mesh.

[@arehman7151]

@@semillerimages Thanks steve, i got it and resolved the issue.

[@hoanglee69]

Where are smoothing factor and smoothing repeat located ? Can you help me?

[@Unreality3D]

Really helpful! Thank you. The first test seems to show that grid resolution beyond 150 doesn't provide a lot more smoothness (at least with these assets). Interesting!

[@Unreality3D]

And you might get even better results just by increasing the wall thickness of your obstacle.

[@semillerimages]

Yeah, seems to be 150-250 is the sweet spot. There was no smoothing of the mesh after the fact either.

[@semillerimages]

The thickness was fine, it's just a combo of the mesh density and the density of the mesh of the obstacle.

[@terryd8692]

I take it that if your resolution is too low you're more likely to get the fluid pass through the container?

[@armiks22]

Thank you.

[@semillerimages]

You're welcome Armiks22 :) I hope it was helpful in some way.

[@nf_felix]

Man really helptull video, took pretty long to make I guess

[@semillerimages]

Thank you and yes, it did take a long time :)

[@RedpaX]

Goodjob. Thank you!

[@semillerimages]

You're welcome!

[@terryd8692]

Very useful thanks! With 2.79 fluid I always found that the fluid never actually rested which was a bit annoying if you're trying to do an animation if a falling glass. The fluid wouldn't spread but it'd jiggle around in an odd fashion. Do you still get that with Flip fluids?

[@semillerimages]

The guy who developed the software might be able to help you out with this. I've never run a simulation long enough to see if it stops moving. I'll have to do that now :)

[@semillerimages]

Running a 5000 frame bake on this same setup now. I'll post the results later today :) Looks like it's going to take 5 hours or so.

[@terryd8692]

@@semillerimages On some of the simulations in this video you get a few stray droplets and they still move around a little. 2:57 for example

[@Blenderphysics-Videos]

What also will affect this is "sheeting" as this adds additional fluid to fill-in holes ;) - so take care when using this feature.

[@semillerimages]

So I finally rendered out a 5000 frame sequence of this same set up and the fluid never stopped moving. Granted, it was very slight movement at the end.

[@mg-se5ws]

what was the size of the actual cup of water

[@semillerimages]

1.4 l

[@mackdaddprod]

I'm curious which version of flip fluids you're using - is it the experimental one that comes with the downloads? Did you have any crashing or problems rendering?

[@semillerimages]

9.0.5 - I had a couple crashes, usually on the high density meshes. I always render to .png files though, so it's a simple matter to just pick up where the crash stopped the render.

[@Blenderphysics-Videos]

With the experimental version you can also start a CMD script and close blender - the script will go on.

[@semillerimages]

@@Blenderphysics-Videos Where do I find the info to do this?

[@Blenderphysics-Videos]

@@semillerimages download the last experimental build. Im also talking about this in my wetmaps tutorial.

[@semillerimages]

Questions are welcome.

[@antheunydu9756]

how many computer do you own ?

[@SeanyKrabs]

I have an overclocked I9 9900k, 32GB of fast ram, an RTX 3090, and it still takes several hours to bake at 200+ resolution divisions.

[@finalresult3d]

That main rendered animation depicts exactly how my 3yr old pours her milk! But seriously this is really informative, good job.
