| Jun 17, 2021 at 22:08 | comment | added | Yousuf Chaudhry | Thanks for spending your time to answer my question. Since I think this solves most of my problems I'm accepting it. Thank you again. | |
| May 27, 2021 at 9:50 | comment | added | Gordon Brinkmann | Then I will have to download it again and make it new. Problem is the next days I just have a crappy old laptop so big files or simulations will not be possible for me. | |
| May 26, 2021 at 19:41 | comment | added | Yousuf Chaudhry | Can you add a screenshot of your fluid settings and the collision settings on the coffee cup? I need help, because the coffee bursts through the cup at some point or another (Immediately at the start of the animation without any surface thickness on the coffe cup) with/without surface thickness. | |
| May 24, 2021 at 13:24 | comment | added | Yousuf Chaudhry | I added the same settings you have, made sure the liquid is not interscecting with the cup, but still it flows out even at frame 1. Can you share the .blend file you edited so I can check what is wrong in my simulation? | |
| May 23, 2021 at 16:54 | comment | added | Gordon Brinkmann | I deleted all animatin except the cookie flying and moved everything to start on frame 1, because this simulation is taking much too long on my PC since my CPU isn't good enough to bake this and let me work on other things at the same time. So maybe it's just because I changed a lot. I deactivated the sprinkles on the cookie and deleted everything that doesn't belong to the simulation. I set Surface Thickness to 0. Also I used 2.93.0 Beta, for the Cache I deactivated Resumable, set compression to Zip, set Sampling Substeps to 4 on all flow objects. In the domain I set Timesteps max/min to 8/2. | |
| May 23, 2021 at 16:31 | comment | added | Yousuf Chaudhry | Can you share the fluid settings on the coffee and the collision settings on the cup? I made sure the liquid was not interscecting with the cup, and the cup is set as a fluid effector as a collision object with 0 surface thickness. The liquid just falls through the cup. | |
| May 23, 2021 at 16:19 | comment | added | Gordon Brinkmann | Hmmm... not on my computer. I'm sorry I don't know what's going on there. | |
| May 23, 2021 at 16:05 | comment | added | Yousuf Chaudhry | Because if I don't give any surface thickness the liquid just flows through the cup, as though there was no cup at all. | |
| May 23, 2021 at 16:01 | comment | added | Gordon Brinkmann | When I told you you don't need a Surface Thickness, why did you make it even bigger? The mesh has a thickness - giving it a Surface Thickness makes it add up onto the mesh as I said before which results in even less space for the liquid. | |
| May 23, 2021 at 12:24 | comment | added | Yousuf Chaudhry | I set the surface thickness of the cup to 2, made the liquid smaller than the cup walls, but still when the cookie splashes the fluid just bursts through the bottom of the cup. What can I do? | |
| May 23, 2021 at 11:36 | comment | added | Yousuf Chaudhry | Ok, I understand your theory. But what steps am I supposed to take to stop the intersection? | |

| May 21, 2021 at 12:07 | comment | added | Yousuf Chaudhry | Ok, thanks for explaining. But, I still don't undurstand that at a surface thickness of 0.6 when the cookie splashes into the cup the liquid does splash, but along with that it also decides to start flowing out of the walls of the cup. how should I fix that? | |
| May 21, 2021 at 12:03 | comment | added | Gordon Brinkmann | No, it wouldn't make the coffee necessarily look more "thin", it is more detailed, finer. Maybe that's what you consider thinner. But in terms of viscosity, a higher resolution doesn't make it thinner, only more precise. Fluid simulation is quite complex, we cannot discuss all settings and effects here, what I usually do is making lots of tests with different settings to see how it affects the simulation - before making a longer animation with multiple effectors and moving objects etc. About the wobble: why shouldn't the coffee wobble? With the cup moving down before this would be normal. | |
| May 21, 2021 at 11:56 | comment | added | Gordon Brinkmann | I think that's exactly your problem - the Surface Thickness is added distance to the mesh to be considered as effector (hover your mouse pointer over the value, it explains what it's good for), and since your coffee is directly touching the cup, this 0.6 additional distance are then overlapping with the fluid - which means your liquid is inside the cup walls so they are not blocking its movement. Even with a Surface Thickness of 0 which would only use the direct mesh as effector you could have this problem, since the fluid is touching the cup so due to resolution there can be overlaps. | |
| May 21, 2021 at 11:55 | comment | added | Yousuf Chaudhry | Another question is that: will increasing the resolution divisions make the coffee loke more thin? And how should I stop the coffee from wobbling too much before contact with the cookie? | |
| May 21, 2021 at 11:38 | comment | added | Yousuf Chaudhry | Wow, thanks! It's a very nice splash now. But unfortunately the liquid bursts through the cup even though it has a surface thickness of 0.6 in the fluid settings. | |
