Video

Thank you! And thank you for sharing your beautiful scene that helped me create this video! I prefer playing around with fluid simulations over modeling scenes/creating materials/etc. And regarding full determination: I'm still running an extended simulation of this video (czcams.com/video/3pEDf4qBF_A/video.html) where I fill up the entire domain with fluid. Right now the stats show 34484 frames simulated and a simulation time of 30713 hours. About 75% of the domain is filled, so just a few thousend hours to go 😅

Thank you very much for that tip, I didn't know that shadow color setting. It look's so much better with shadow color set to white! I will upload the re-rendered version as soon as it's finished, probably in two to three weeks. 🙂

Took a little longer but here is the updated Version 🙂 czcams.com/video/gfRs66366Kw/video.html

Sorry for the late reply, I'm not very active on CZcams at the moment. The resolution is set to 1100. Unfortunately I deleted the FLIP Fluids stats files so I can't say exactly how long it took to bake - but it was in the month range. I simulated all 12 Presets but most of them looked pretty similar, just with different colours. So I didn't put every one in the video. Based on the timestamps of the files in the project folder, I started this project early July 2020 and the last frame was rendered in December 2021. I originally wanted to include the baking time in the description but then thought that would be pointless as I used multiple different machines for baking/rendering and couldn't even remember which Preset was simulated/rendered on which machine 😂 Most of the simulating was done on a Xeon E5-2665 and rendering on six cores of a Ryzen 7 3700X.

Thank you! These are materials that come with the FLIP Fluids addon. The copper material does not glow at all. So you're right, it's not very realistic. But I think it still looks cool because it's something different. The only metallic "liquids" in reality that come to my mind at the moment are something like mercury or car paint.

@@mscsaa well here's some metals I can spontaneously remember that are liquid at temperatures not high enough for them to glow: cesium, potassium, lithium, indium, lead, tin, zinc and I'm sure some more that I can't remember

At high enough flowrate the experiment loses its purpose. Put it this way. You have in this arrangement 1 cubic kilometer tanks where the flowrate cannot be high enough to make a difference. F will always fill up first. People just want to cheat the task saying they found a different solution. Yes the flow rate is not specified but it should be reasonable to have a source where the water flow rate does not exceed the flow rate of the pipes.

:-D There is always something rendering oder simulating. I just got a bit lazy with uploads. But now I'm cleaning up my hard drive and will finish what I have laying around.

I'm not sure what you're trying to say, because F IS the cup that fills up first in this animation, too.

@@StormBurnX no c did

@@Dhruv1223 I don't know how to explain this but they literally numbered them based on the order they filled up at the end. Additionally, at 1:37, F is already full and no longer has input, whereas C isn't visually full until at least 1:50, and the flow doesn't actually stop until after 2:25 All the info you need is right there in front of you

I think I ran the simulation at 1000 FPS and the render at 25 FPS. But I'm not 100% sure on the simulation value, I can't remember correctly :-D

Renderings with bubbles and foam always take longer because there are more small details. And the RAM usage is higher. So a problem could be that there isn't enough free memory, so the swap file is used which increases loading times.

Yes, I already ran a few test-simulations for that. It's a bit tricky to get the amount and stickyness of the chocolate right so that it looks good.

WTF, a random springle yeah. Ah, he also said it in the description

Thank you! I simply set the fps to 200 (or an even higher value) when simulating and rendering. And when I combine the rendered frames into one video file I use 25 fps.

@@mscsaa Ahh I see,so do you also have to increase the amount of frames in the timeline to render ? because say you choose 200 frames per second and you want the animation to last 10 second,so you would then set the amount of frames in the timeline to be 200 x 10 = 2000 frames ? so that you can do the slomo in say premiere pro by bringing it down to 24fps as you mentioned ? am I grasping this right ?

@@Mbg-tech Yes, this is the way I do it.

I built a dedicated PC that I only use for simulating and rendering and let it run 24/7. And thankfully the FLIP Fluids Addon and Mantaflow allow to stop and resume the baking process if I have to reboot the machine.

Its blocked, check again

Yes, you can use it. :-)

@@mscsaa many many thanks!

I modeled this after a 2D riddle I found online. C to D was blocked in the original, too. Probably to confuse people an make the riddle a bit harder to solve.

MSC Simulations & Animations I always wanted D to fill up first

@@extrauser1498 I think if C to D wasn't blocked, G would fill up first and D second.

MSC Simulations & Animations then add a pipe from G to F or H

The water material is just glass with an IOR (Index of refraction) of 1,33 which is the correct value for water.

@@mscsaa Nice, thanks!

The trapped air is just ignored, so this isn't physically accurate. I don't know if there is any fluid simulator for Blender that takes trapped air into account when simulating the fluid.

I super appreciate these videos, and you're right they are flawed on several angles But it does get the brain thinking about the subject in a constructive manner, and they're fun enough to draw attention

@@mscsaa one workaround is to first fill everything with a fluid that you set to be physically equal to water (I don't have Blender but this may work)

Thank you! And sorry for the late response. I think this is the HDRi I used in this project: hdrihaven.com/hdri/?c=sunrise-sunset&h=pink_sunrise The floor is one of these concrete materials: store.chocofur.com/free-concrete-shaders/blender_model/blender-3d-cycles-shaders-materials-free-concrete-beton And for the fluid I used the ocean material that comes with the Flip Fluids Addon.

Yes, the particles are icospheres. And the material is a mix of a glass and a diffuse material if I remember correctly.

That's an interesting idea. Maybe I will try to do something like this.
