OMG I can't wait to get stuck into it! I appreciate the effort you have put into this video...and yes, you got my name spot on :) Cheers Dean, keep the great content coming. Glad you are putting out videos for this very specialised topic.
Thank you very much. Hope it's helpful I'll also work on some other physics simulations soon
I am watching this video 2 years later and it is still very useful and helped me a lot, thank you so much! I am sure you are still helping many others like me and that is very much appreciated!
Same
I guess nobody talks about this but your voice is fricking awesome
😄
Quick tip, when you're working on other stuff, you can "disable in viewport" the liquid domain,
Your object list>funnel icon top right, tick disable in viewport>click on disable in viewport icon next to liquid domain object
that will speed everything up until you're working on the liquid material
This was the exact channel I was looking at. Can we have more cloth, softbody... Etc simulation coupled with water. There could be so many cool things that way.
Thank you SO much, you cleared up so much that was driving me crazy to try to learn. I'm so excited for my rendering to finish so that I can make an animation and post it!
Really glad it could help looking forward to seeing what you create
Fantastic!! Many thanks, my Friend.
A really great tutorial! Thanks so much!
Glad you enjoyed it
Water flowing through a pipe was my first attempt at blender and I couldn't find the settings for using the pipe as guide for the water. Everything works fine following your tutorial. Very well explained for absolute beginners, thank you!!
Glad I could help!
I’m getting some success with these videos. Thank you! You explain things well. Pushing other objects around with water would be a fun thing to see. Like a water mill or something
That sounds like such a nice project great idea
Your tutorials are amazing!
Thank you very much
This is awesome tutorial! Thank you!
Glad you enjoyed it!
Nice work, and thanks for the explanation
No problem 👍
Learned more here than anywhere else. 👍
Glad you enjoyed it. More videos coming again soon
Great to see a fellow Saffa in the 3D community :D Could recognize that accent in the first few seconds. Great tutorial! Thanks for the effort.
Thanks man. Yeah we need more people here to get interested in 3D and such. It's a growing field and people need to jump onboard
thank you for your useful videos.
You are welcome!
excellent video
very much appreciated!
Thanks for watching
The best fluid course definitely, finally I did fluid right! Would you like to continue physics simulations? Could you please make a bowling simulation? I used rigid body simulation for this, but it does not work in a right way. Thanks for the lessons!
Great suggestion!
A great tutorial 😍...will definitely try this out tomorrow...
Could you do a tutorial on a whirlpool??😁
I'll definitely look into it for you
Many many steps. Thanks for letting us watch you create. PROJECT: We need to animate, somewhat, a painting still life, to make it eye-catching and suitable for NFT. Not weird, but tantalizing. (PS: To follow at all, I had to run you at 0.5 speed and review many parts.)
Thank you very much for your input. It's much appreciated.

Can you kindly upload a video on Gas flow through pipes with changing colors at every process, like in a compressor, or in pipes.
Thanks! Waiting for your response.
Could you do a tutorial with how to make dirty liquid. There I mean water with large chunks in it. Would be nice to see your reaction, kind regards.
Now scale every thing (domain, pipe, sphere) up like 100 times and bake it again but it does not flow anything, do you know why ?
Is Mantaflow the default in Blender, or do I need to find an addon?
Thanks for the tutorial! Does starting with a plane make this possible? I modeled similarly but using an archemedian curve so the planar fluid selection won't work. Any ideas?
Hi there, thanks for the comment. You should still be able to use it as long as an end is open and the water has somewhere to go
If anyone is trying this in 4.1/4.2 it's possible you need to turn your Y velocity up some. Try turning it up to 50-200. You can also try turning up the Sampling in the domain object to spawn more particles.
100% this video has become dated rather quickly. I have recently started with 4.1 and have found that things have changed for blender liquid sims.
@@vgleviathan911 still appreciated this video a ton! Things like this are very helpful for us noobies just starting out. 🙂
@VG Leviathan is there a way to fill a pool up and when it reachs max the water stops flowing, its for a game I am make with UE 5 its going to be a Coolant Pool for a Reactor.
This is an interesting project does it only fill up once? If so you could use key frames to stop it when it gets to the right point switch off the flow
@@vgleviathan911 I currently purchased fluid flux off epic games marketplace I am thinking would it be possible to make a pipe and have a resevour where the water is stored then have it flow through the pipe??
This is great, thank you! I am a newbie to animation and found your video while looking for a way to simulate 3-phase flow in a pipe (gas + oil + water) using Blender. Do you think it would be possible to extend your technique to 3-phases?
Hi there do you have an example of that?
@@vgleviathan911 hi thanks for responding! I am a (retired) process engineer who has written an Excel spreadsheet for calculating the size of the separator tanks which are used in the oilfield for separating incoming mixtures of oil, water and gas into their individual components, and I want to create a youtube presentation which illustrates how to use the spreadsheet. This video (not mine) shows a typical separator: th-cam.com/video/xgLOU4EwC0o/w-d-xo.html. This morning it occurred to me I might try creating 3 pipes such as yours, separately flowing oil, water and gas, then somehow combine the outputs from the pipes?
I'll look into it for you and get back to you as soon as possible
in my experience this is simply not possible. Even with phoenix FD witch is widely considered one of the best sim programs. Anyway if it is i would love to know how. I have been able to cheat this effect with some shades but the result was sub-par. or even with "fome particals" -not so good
This video is very helpful!! Thx for uploading. However, how can i decrease the flow a little bit cause it seems too much for me...?
i think he explained that in part one of fluid tutorial, im not sure tho
In the in the settings for the emitter there is flow and you can turn that down
In initial flow in the source
Wow it's like a little community building here. I think it's great when others help to.
Did the suggestion from TheCoolestWolf257 work?
Excuse me, do you know why I can’t not bake mesh😅
Is it possible to start off with a body of liquid and have an object rise out of it?, Thank you.
It's definitely possible great idea for my next video
@@vgleviathan911 Please make a video on this. I am also struggling to achieve that. Thanks!
Anything, is possible
What kind of graphics card do you have if you only say that the baking will take just a little bit longer?
I have no graphics card at all. I have an I5 with HD500 graphics
Hello, very good video, I wanted to ask you that in my project very little water comes out, how can I make more water come out, thank you very much!
So you'd have to scale it up and increase the water resolution. Keep in mind increasing the water resolution increases the load on your PC and Al the bake and render time
@@vgleviathan911 thanks so much!
Hope it helped
I have a question: water goes into the tube but there are some particles coming out of the path and not following
Try increase the resolution of your particles and bring down the initial velocity
Hi im new to blender, i was wondering can i use it to a model of house? Then it makes a flood
Hi there I know you can model a house with it. I have a friend who models homes for a living using blender. As for making a flood. This is something I haven't done personally but i'm sure you can with some practice.
Hi VC Leviathan!
I am following along with Blender 2.90.1 and there are some issues...
- Increasing the time scale will increase the speed and not decrease it. Your settings will produce very slow fluid flow.
- Then, the water flow will be weaker than in the video. I set Y Initial velocity to 5 m/s and it improved. But still, I get mostly blue particles. I am not sure what the default particle colors mean, but my water feels more "calm" than yours...
Thanks for the great work!
Hi there. I'm using 2.8 at the moment but I'll have a look at 2.9 play around with it and do a video on it.
@@vgleviathan911 up the Y velocity to 100+ and it works the same in 3.0 :)
Hi! Your tutorials are fantastic! I'm trying to fill a water jug with liquid, so it stays full, but the water will move if you move the jug around. Is this possible? If so, how do you do it? I'm having a really hard time figuring it out!
Hey there thanks for the great feedback I'll get to this one as soon as I can. Been getting a lot of requests. But I'll tackle it asap.
How do you get water to collide with an object? And how did you render the full water simulation? Because usually it just renders the picture, was it made by rendering all the frames and putting it in the video editor?
Hey there yeah so I render all the frames and then sequence them in the video editor
Yeah I render the frames and then sequence them in the editor. To have water collide with an object you set the object to effector in its physics properties
@@vgleviathan911 thanks
Hope it helpes
At 14:43 Your Liquid domain is visible in wire frame. But when you switch to solid it disappears ? How did you make the cube disappear? For me the box is a solid cube and blocks my pipe / fluid? (I probably missed a step, 2nd ever time using blender :S )
Edit: I had to bake the settings and also the fluid mesh. I didnt realize they were two diffent bakes.
I'll make sure to specify the different baking in my next one
I have the same problem. Could you be more specific about how you fixed?
some of the water particles got stuck on the inside of the pipe for me? do you know why?
Could be the particles are too large so try raising the value of the resolution in your domain settings. Or it water being left behind in the pipe.
HI. Anyone can help here. Whenever i go in rendered or camera mode i see the domain as a block and cant see the simulation inside. Anyone can help plz
Yeah so this will happen untill you bake your mesh
I imported a model from solidworks and follow the above but with model it doesn't work and without model it works ...
Subscribed :)
Many thanks! Hoping to make a return to TH-cam soon
How do you bake so fast!?
The baking speed depends on the amount of RAM your PC has and the resolution of your simulation. Higher resolution equals longer bake.
why is my water is so slow? i already increased the velocity and seems like there is no change to the amount of water produced,hope anybody can help thanks!
Hi there. In your domain settings you can increase the speed there
Fluid flux 2.0 for Unreal
Bro how to push the water in opposite direction. in tube does not have that much video in TH-cam u made that it will useful
Many thanks my friend
when I do ctrl alt 0 it doesn't change the camera position how do I do that?
Doesnt work for me too but you could just go to the View tab on the right and look for Lock camera to view. Just pan around to get the right view then disable it after.
@@losneor
ok thx
Also the shortcut is with the numpad
Can I do this in Blender 2.9
Definitely
Can you share the blender file?
I don't have it anymore but I'm redoing the channel soon with Blender 3 and Up. I sadly had to take an absence from my teaching for a while.
I have a really small sphere and it's doesn't work, have you an idea how to resolve this pls ?
If your sphere is too small you domain resolution need to be raised making the particles smaller
@@vgleviathan911 Yes, I have found, thanks! but my pc lag a lot with to small resolution, so the best think to do is scale a lot. at least you don't have to reduce the resolution
I saved my progress after finishing this tutorial. When I opened that project again it doesn't start from first fps. It doesnt play at all. Why is it so? Maybe I do something wrang? Please help?
Hi there you have to make sure you are saving your project correctly
th-cam.com/video/057YC-f6GCw/w-d-xo.html
Have a look at the link I sent you it will help you set up your save file correctly
@@vgleviathan911 Thank you so much. It's very useful for me. You are a good teacher!😊
Can you simulate two substances: water+air? Maybe the air could be another liquid with density of air?
Good question. What is your project idea so that I can get a better understanding
@@vgleviathan911 With air+water simulation it would be possible to simulate and design vacoom applications.
can you share the project file?
I sadly no longer have the file. I do, however, intend to do it again soon, then I'll make it available.
How do I wind to effect water?
What exactly do you want to do?
@@vgleviathan911 I want to do a scence where its like moses parting the red sea. But instead of the red sea its a kiddy pool. When I use the wind effects its either not strong enough or then it jumps to way too strong and makes the water fly everywhere
when i increase the size of the water domain the size doesent increase instead the place moves what to do please help
Hi there try freeing the data and baking again
@@vgleviathan911 i am not able to bake when i start baking the blender crashes what to do please help
Are you using a stable build?
For some reason, I can see the particles in the mesh but not the Water. Can you please help me?
Hi there what do you by you cannot see the water?
@@vgleviathan911 So when I baked the water I could only see the movement of the particles and not the water.
After baking mesh
Ya same after I bake it I only see the dots and not the solid liquid
Did the same thing as u (but with smaller sphere and pipe), and it doesn't work, water doesn't get out the sphere
So iv noticed with this simulation I had to scale up the pipe and sphere. Also set the resolution for your water to at least 100. U can do it in the domain settings
@@vgleviathan911 It works, tysm :)
Anytime 👍
Does anyone know why the Domain is still visible for me? Even in the Solid Viewport it's visible and I can't see anything inside it. I know I can click on X-ray, but it will still be there in my render. (I think)
It will disappear as soon as you bake your mesh
@@vgleviathan911 really? I guess I’m not really sure what baking is😅 thanks buddy🤗 I’ll try it later, this is a huge help for my project❤️
No problem at all. You'll see it in the video
@@vgleviathan911 Yeah, I think I've just been trying to many things at once x) I just started using blender 2 weeks ago and I wanna try everything. It's just difficult to make it all work :) Thanks for your tutorial, I really appreciate it - and your answer
can someone plz help me, the water from the sphere is leaking outside of the pipe instead of moving in the pipe.!!!
Try udjusting the particle resolution higher if the resolution is low the particles are too big to move through the pipe also try baking the simulation again
@@vgleviathan911 Thank you very much sir for Replying me, Actually I am watching your video for my uni project and I need to submit it till tomorrow , I tried It alot.. It will Be really appreciated If You can Help Me Personally through team Viewer. I have Subscribed your channel And promise To Share Further with My friends and family , Thankss.
Ey buddy I'm unfortunately unavailable today in future though will definitely be willing to help.
@@vgleviathan911 Thanks Alott sir.. I was Able to figure out the Problem ,, Still Thanks Alot.. You video Helped me Allot!!
Glad could help what are you studying at university?
Very good tutorial, thanks. don't posible to do it in French (joke)
nothing happens after baking. i can not see particles
It's very possible that your cache is corrupted. In which case you may have to re do it with a fresh cache
I dont see nearly that many particles?
You can increase the resolution in the domain settings this will increase the number of particle. Keep in mind though it also takes more resources when doing so
you sound like dani
🤣
while i do think you explained it pretty well and it is helpful, i think if you just showed the steps clearly and edited them effectively with some post pro commentary this whole video could have been 5-6 minutes long, which i would like more... but still nice work
Much appreciated 👏
Bro why is your voice only in my left ear.
No idea mate. I'd like to know if others have the same issue.
You sound like Dani
It's so weird, you are not the first person to say that hahaha
But I am South African
normal people: excuse me, i need to go the toilet
nerd: i have to let some liquid through pipes
super mario: nice pipe!
I wish I could post my animation in a comment -sigh-
Feel free to post a link
Love your animation. The glass is an awesome touch. Well done
I’m going to have to go over this video maybe more than once cos you lost me over resizing the pipe. Mine looks fat whereas yours looks like a proper pipe.
So to resize the pipe u resize the bezier circle. This is before you convert the pipe to a mesh.
Not working did it all no water at all
1) Try enlarge the pipe and sphere.
2) make sure that "is planar" is selected for your pipe in its physics settings.
3) Make sure the resolution of your water is set to at least 100 in the domain settings. If it's set lower the particles are to big to move through your pipe.
Please let me know if this helped
dani?
?
for a moment your voice sounded like a dani on autotune
Hahahaha no. So my question is... Does that mean my voice sounds good or terrible?
@@vgleviathan911 very good
Over time i became infuriated about the invisible wall so i deleted the wall to make water flow freely
It was a disaster
Hi there, sorry to hear about your frustration. What wall may I ask are you talking about?
Nvm i learned why theres some sort of invisible wall thing , sorry to bother you
@@kerb525 No bother at all
south african
I am indeed
This crashed my Blender.
Sorry to hear that what machine are you running? Perhaps try doing it in Eevee if it's too intense for your PC
@@vgleviathan911 Man when I pressed play with a resolution of 150 my PC's fans went into maximin overdrive.
That animation looks really bad. A lot of simulation programs aver very specific to the size of the simulation. I'm not sure what the preferred size is in blender, but it should make things move in a much more realistic manner if you find it. Generally, If you go too big, everything moves in slow motion and if you go too small, everything moves too fast. Another issue is the Meshing of the water is way too blobby, making it look very unrealistic.
So far I haven't found anyone doing anything more than the basic "look, it's water" with the same crappy results. I guess that's what I should expect from a free package.
Hey man I'm sorry you that way. So at the moment my tutorials focus on people with standard to low range gaming computers. If you have better hardware you can achieve very realistic animations and simulation.
