Questions tagged [fluid-simulation]

Questions about the Fluid simulation systems in blender. Blender has two systems for simulating liquids, a SPH (Smoothed Particle Dynamics) system integrated with the particle system, and a Lattice Boltzmann method which can be used create a variety of simulations.

Water leaks through obstacle

Every time I try to hold water with a obstacle, it leaks out. Here is one example I have made. The shape has no holes, and the water is partially contained but slowly leaks out. This has occurred every time I have tried this. What could the cause…

River simulation - different approaches than fluid simulation?

I am in the middle of a project which needs to have a river flowing in it. (You may be familiar with my recent questions; they are all related.) Just for reference and imagination, here's a preview of the setting where the river should go. As you…

Simulate objects falling into water

On the blender website there is this image: What would I need to do to recreate this, cubes and spheres falling instead of fruit would be fine. I believe this uses the cycles render I have never used this before.

How can I make drops of fluid hang from a surface?

The images below display the kind of effect that I'm looking for. A combination of surface tension and intermolecular forces make drops of water hang on things (though they may occasionally fall off depending on the amount of fluid in the drop). I…

How to avoid fluid appearing outside collision objects?

In fluid simulation as it is done on a grid with a resolution definable even choosing a higher value for the resolution (as in our example below, 200) it is not enough to have a realistic shape of the simulated fluid with respect to the obstacle,…

How to stop fluid inflow?

I have fluid simulation with an inflow object. I want the inflow to go for 2 seconds, then have the inflow stop (so no more fluid is added) but keep the simulation going (so the existing fluid sloshes around). However, I do not see any way to set…

How to completely fill an object with fluid?

I know how to make obstacles and inflows in Blender, but I do not know how to simply select an object and have it be filled totally with fluid. What tool/command/setting do I need to have an obstacle become filled with fluid?

Fluid not showing in fluid simulator

These are the settings of the flow object and the domain object. I think I got all the settings right but every simulation I bake does not show the fluid. I tried restarting blender but it keeps doing this. I checked the 'liquid' tick box and it…

How to create a continuous flow of water?

I have built a water slide and pool and I want to make a animation of the water running down the slide and into the pool. The problem is I need the water to be created at the top and go away at the bottom to create a continues stream of water. What…

How to make beer foam

I want to make a beer foam, not just for an image. I want the beer fluid to pour in the glass and automatically make foam on the top of the glass and drop down due to over flow. It should be in animated not a static render. I have seen video that…

No "obstacle" option in fluid type

I'm trying to make gas flow through a tube. I've watched many videos demonstrating similar procedure. And they simply add a cube or any other object, go to the 'physics properties', click 'fluid', then choose type as 'obstacle' In their screens, the…

Water simulation (direction / pressure)

Do water simulations in Blender only go horizontal and down, or can you have water go vertically up from something like a fountain?

Problem with fluid simulation, cannot get fluid to move up a thin pipe

Hi all So I created a little pipe system which I require water to flow through. It's meant to start by the water getting sucked up through the thin pipe currently located in the water and then flow through the rest of the system. I have tried to…

For Fluid Simulation, what do the Start, End and Speed settings mean?

How do the Start, End and Speed settings work? Isn't the Speed setting determined by the Start and End settings? For example, say I have 120 frames (at 30fps, thus 4s), and I set "Start: 0", "End: 8", then the fluid will move around twice as fast…

Blender Fluid Sim, Realistic Vomit?

I'm trying to use the fluid sim to create a vomit VFX shot for some live action footage I've got. But I'm struggling with getting it look the way I want. So far this is what I've got: I'm relatively happy with the way it lands on the floor (except…
