Fluid Simulations for Beginners 💦 (Blender Tutorial)

[@prazo_20]

Usually after I finish watching a 1hr tutorial video, I feel scared to start sth new, but when I watch this guy's videos, I feel like I already know what to do and how I wanna do it. That's how I learnt how to animate anything using his animation beginner tutorial. That right there is a rare gift.

[@RyanKingArt]

glad my videos help!

[@etn249]

Pretty nice and complete as a begginer tutorial! I would like to point out a few simple settings that will easily improve the result even more, if anyone wants to take it a bit further. - On the domain, the "fractional obstacles" checkbox can improve the flow against diagonal obstacles and help with the water getting stuck in a stair pattern on the slope. - In the "mesh" section of the domain, you can set the "upres factor" to 3 and get a much more detailed mesh for the same simulation. - Still in the mesh section, you can check "use speed vectors". This will allow the fluid to have motion blur at render, which will make it a lot more realistic. The cache format needs to be set to "uni cache" for this to work.

[@nasimajosefi]

Just want to say THANK YOU for all effort you put into this videos. they are extremely educational

[@RyanKingArt]

Glad you like them! thank you for watching!

[@RyanKingArt]

Thank you for your support!

[@capalmer2495]

This was great. Thanks. I think another really important tip for beginners is that fluid simulations work much better at large scale - even if you have a great graphics card. So if you are modeling something like a faucet, don't use real world scale or you will end up needing a resolution of 200-300+, it will take forever to bake, and you will still struggle with effectors not working properly (e.g. fluid through the mesh). If you scale everything up 5-10x you can work with lower resolution and get much better results. I've learned this the hard way.

[@Timelessvisuals-c9n]

Clever trick …i see how that would work 😮

[@j16180]

This was extremly clear and easy to understand, I didn't even feel the need to rewind to listen again in any point

[@MercuryRisingFast]

Ryan is the best, that's for sure.

[@360creative_pl]

Great tutorial, I just found 1 confusing thing. When the water goes thru the effector, you say that the solution is to increase Resolution Divisions. What helped in my case (I was doing my own scene, very large objects and a looot of water ;) but I wanted to learn about the fluids in Blender from your tut, which was great), was the Surface Thickness in the Effector settings. I had to set it to 0,5 and it worked even with very low resolution divisions. Thanks anyway, great tutorial!

[@energetic0oak329]

you just saved my life, i had no idea why it wasnt working, just thank you.

[@JohanPeeters-no9yo]

Thank you!

[@josephcowan6779]

thank you!! I was just trying with a basic box and I was wondering if it wasn't working because it wasn't thick enough

[@DES1GN3R007]

[@llYuki0okami]

If you want to set up a very small fluid source, set Flow as mesh plane with IsPlanar checked and resize it as much as possible, the effect will now depend only on ResolutionDivisions. To reduce the fluid even more and give it more character, add to your FluidDomain a Displace Modifier with Strength eg -0.02 and after it a Subdivision Modifier to remove the resulting artifacts. Remember that this sometimes breaks brush painting with Dynamic Paint. Also, I had a case where I was using two separate fluid domains in one place and wanted to use them as a brush dynamic paint, but either one or the other didn't work, adding them to one collection and using the Brush Collection in dynamic paint options helped. Sometimes it happens that when we attach Flow mesh to the armature, the fluid simulation will not work, you need to bake the Flow mesh movement and detach it from the armature.

[@RyanKingArt]

Thanks for the tips! 👍‍

[@Gregory_Harshfield]

Thanks! So, hypothetically, we have a scene with a great deal of steam coming from vents, is it better to bake the steam, than add it after creating a scene for rendering purposes? Plus, what should we think about in regard to scale when it comes to using simulations for a set piece that might be extraordinarily complex?

[@RyanKingArt]

Thanks for your support! I would recommend baking simulations at the end of a scene creation, because simulations can slow down the viewport, and if you change something in the scene, you might need to re-bake it. And yes, modeling to scale can be helpful, to make the simulation look more realistic and to have a more realistic simulation speed.

[@Gregory_Harshfield]

@@RyanKingArt It was good times! There is no shortage of tuts on fluid simulators, but you avoid the fluff and unnecessary, if not infuriating, sidenotes to amuse, and you have a pristine attention to detail. It is going to be time for an RTX video card in my future in order to do the things that I want to do that will be compatible with Cycles. Going forward, I would love to see a tutorial on retopology for characters in order to hit up UV mapping and procedural textures on sculptures/figures with intentions to animate while reducing rendering times. Thanks, Ryan.

[@RyanKingArt]

thanks for the video ideas!

This is a very fine tutorial. Ryan clearly puts a lot of work into the structure of his presentations.

The force is strong with this one :) Can't wait to toy around with all this and so much more and especially integrate it into a complex simulation for most of my inventions (from al things architectural and urban + interior design, vehicles, clothing and footwear and practically all sorts of objects) And also, I'm quite curious what the 5000 series will be capable of :) Especially in your hands :) may the FORCE BE WITH YOU !

Finally a water simulation that has a reality gravity, not like slomo water stuff. But I hope in the future tutorial when you want to make a water simulation, just add motion blur whatever in post or in Blender native motion blur to add more realism water motion...

First off I've been using blender for about 7 years giver take. I've created muscle memory and then I didn't use the program for a long time and then created muscle memory and then didn't use it for a long time. I've watched hundreds upon hundreds of tutorials online from various people. Your tutorials by far are extremely exemplary! I watched a lot of Ducky video Tutorials. By far you are the best at explaining. U take the time to teach people and that's amazing you don't skip over anything. I am just so impressed with your tutorials and your ability to create a immersive environment in which to learn them. I just have a question. I did this tutorial and when I added motion blur it made it look like it was gaseous. I've spent hundreds of hours watching your videos and trying to emulate what you do. You are a freaking genius. Thank you for all that you do and I wish that I could support your page, all your pages I should say. I'm just broke as a joke. You are a huge inspiration!! One last thing, if you don't mind me saying is that, I use Imperial. I don't know metric. It's possible that my viewing instructions might be different because I don't use metric settings. Your input would be greatly appreciated. Ty

How did you learn blender? What courses did you complete for that? Or did you learn blender software only through youtube channels? If you can please reply for this

[@AlfredWolfstein]

If your fluid is going through the slope, a possible cause is wrong face orientation in modeling. Click "Face Orientation" in Overlays, and the blue side of the slope should be facing outwards. If the red side is facing outwards, go to edit mode and flip it.

Hey man thanks so much, this and the cloth sim tutorial have been extremely helpful, and your teaching style is excellent. Perfect amount of repetition / reiteration in certain areas. Just one question though, is there any particular reason you use the denoiser in the compositor as opposed to using the one in the render settings?

[@moharmon770]

I've wondered about the denoiser as well. I remember a couple years ago some KZbinr suggesting using the denoiser in the compositer (with "Denoising Data" checked on, and Denoising Normal and Denoising Albedo plugged into the Denoise node in the compositor) so that's just how I've done it without really knowing why. But now in 2024, is there a "best" way to do it? Is some version faster / is some version higher quality but slower?

Awesome tutorial! This is a great place to begin, well-explained and a good pace. I have a question to take it further though: if you want to the fluid to not be uniform (lava flow is my ultimate goal, but same would apply to dirty water or mixed color paint), can you MIX two materials together in the fluid simulation?

[@main-wayout]

Thanks a lot.

[@RyanKingArt]

you're welcome!

[@HandsomeDragon]

It took me a while to understand why I wasn't seeing my simulation preview in the viewport. The reason is because, when set to "Replay", it caches the sim, and if you make any changes those changes won't update, because the cache is still there. To reset the cache, you can change the resolution-then back to default again. For example: You played the sim at 32 rez, so reset set it to 34, then back to 32, and when you press Play you'll see it updated.

[@zergidrom4572]

+Some tips for those users who doesn't have 128 cores threadrippers... •domain size *must be* as smaller as possible because mantaflow optimizations is somewhere near titanic's current position and it would calculate nothing most of the time.This small thing could save plenty of hours of baking time. Also smaller sized domain could have less resolution than poorly sized one with bigger resolution with the same voxel size which also means less calculation time. •always use particle size 1.05 •Diffusion 1000000x > viscosity •Adding Smooth modifier on domain for render with facfor=1 and ~5repeats *drastically* increase quality of lowresolution mesh •you can never touch "mesh" settings on domain. completely gives nothing except wasting time to play with them

[@tomdejonge8709]

Maybe this will help some people, this is what worked for me The icosphere isn't making water -> delete the icosphere and remake one that hasn't been scaled down too small The water keeps clipping through the slope completely and going down in a straight line -> Make the slope and the cube two different objects The water keeps clipping through the object even though I've raised the resolution to 100 -> Size everything up a lot except the icosphere.
