Hello everyone, I have some floating RBD pieces on FLIP fluid particles, and I would like to manually define the mass (density) attribute for each piece. Is this possible? Thanks for helping.

Hi guys, In a Flip-Fluid simulation, I want the fluid particles to enter and trap in a closed collision volume (I mean an Invert-Sign volume). I applied these settings: 1) "Static Object->Collisions->Volume->Invert Sign" to on. 2) "Flip Solver->Volume Motion->Collisions-> Transpa...

Hi guys, When I fill a cup with flip-fluid, I suppose the particles have to fill any gaps between the interior surface of the cup and the fluid, but as you can see in the image below, the outer surface of the fluid has some wrinkles on it. In this simulation, no viscosity or surface tension is...

Hey guys. Need some help with collision geometry for a Flip sim. In the attached you can see the original geometry in collision source, and the resulting voxels in #2. The geometry is sourced from external .objs that I have merged than applied a Boolean Union operation to. Is there so...

As you can see in the image below. If the rigid body is on the left side of the merge node the rigid object doesn't obey the force of the flipfluid and if the rigid body is on the right side the behavior is odd. what's the correct workflow?

Hi guys, I tried to use "RBD Packed Object" + "FLIP fluid" and as you can see in the image bellow, the boxes sink into the fluid after a while. How can I fix it? The DOP creates some volumes inside the boxes, and I guess they are somehow a collision volume representation, but I don't...

As you can see I used a guided ocean layer from the shelf, But the interior volume doesn't obey the extended surface size. How can I fix that?

There's no explanation in the document to create a slip control field for viscosity? Does anyone know?

I have tried a lot and i just cant understand why my particles are dying and volume is reducing. I am trying to make a washing machine animation with the water. Any tips? Any suggestions would be appreciated :)) untitled.avi washing_machine.hip

Hello, In a small-scale FLIP-Fluid simulation, I need to improve the flow of fluid particles, so I tried these settings: 1) FlipSolver -> Particle Motion-> Reseeding -> Surface Oversampling = 20 2) FlipObject-> Particle Separation = 0.01, Particle Radius Scale = 0.66, Grid Scale =...

Hi everyone, If I have many emitter source in Flip DOP and I have one of custom vel for volume velocity by copy. So if I want active force on just one of all emitter source but I want to make all of fluid from many emitter still interact together. So how to mask volume vel or how to tell volume...

Hello; I would like to create a scene (artist brush hairs collide with an oil color liquid) like an image below. I tried to make a collision between some vellum strings and a high viscose flip fluid, but it doesn't work. Is vellum suitable for this situation? Thanks for he...

Hey wizards! So I'm working on a project and I'm tasked with doing an inverse whirlpool. I've tried several techniques like curve force and axis force but they become unstable and don't give the desired effect I need. I'm currently using pop particles to affect the flip and it works, bu...

Hello; I would like to create a colored fluid, with thin streams like the image below. I added some velocity noises to simulation, but the result is poor. Thanks for helping. Colored_Fluids_01.hip

Greetings, I'm doing a basic flip simulation where I fill a cup with liquid and then I rotate the cup to spill the liquid into another cup. Sounds super easy and basic, but after some time fine-tuning the collisions and the liquid I can say with certainty that my liquid volume is getting l...

Hello; In a Flip Fluid simulation, how can I stop particles to shrink down? Thanks.

Hi, I have seen this posted a few times but no clear explanation on how to get it up and running. I created a simple drop of water with a small crown and a single drop on the top. its client likes it but when I up rez it, the simulation changes. is there a way to up rez and the simulation not...

Hey all, I am relatively inexperienced with Houdini and very new to Flip Fluids and having some issues with my simulation. So I have created a container, which I would like to fill with a fluid. I am trying to make it so that the fluid flows into the container and half way down interacts...

Hi there everyone. I have this very Unique issue that is both on Windows 10 and Linux (Mint 19.1, Ubuntu 18.04, fedora 29 and 30) where I will run a Simulation (Pyro, Particles or Fluids) and it will say Complete but only do 159/600 frames. The number of frames it dose is random and could cha...

Hi guys; I would like to learn about how to use Ocean tools + Flip FLUID to create a scene like " Whale jump ", so I started with a very basic scene like a sphere jumping out of ocean... In ocean shelf tools I tried "Guided ocean layer". It works fine, but 1) I don't know how could I...

I have a simple setup with rbd packed objects falling into a flip fluid. Maybe my solver order is wrong but when the objects hit the flip fluid the liquid explodes with so much force.. Ive uploaded my file. How do I make it so the the objects hit the liquid in a natural way and sink to the bott...

I want to do super slow motion of cheerios falling into milk flip fluid. When I change Scale Time from 1 to 0.1, some of the collisions cause explosive behavior. Someone suggested I write out the sim files with Scale Time set to 1, but substeps increased. Then read the sub stepped sim files as... -
Hi, I'm trying to make two flip fluids interact with each other, but it doesn't work so far. Also, I would like to assign different colors to these liquids. flip_test.hipnc -
Hello, I would like to interpolate the points of a flip fluid to test the slow motion. The problem is that the ptnum of each point changes over time. Do you know how to fix this problem? Thank you very much, Brice

Here is an RBD of tori falling into a flip fluid, with Scale Time at 1. https://drive.google.com/open?id=1CZRguzia-uBbav6sb6Ln4zxRYnAOJbdf [drive.google.com] Which appears to be working fine. I want to do a slow motion version. So I tried reducing the timescale setting on the dop netw...
