Hello everyone, I'm working on a very specific earth/ground blast. Inorder to keep the max control I decided to create pre sim wich would be used as a source for the main simulation later. Or I'm going to build it in directly and blend it with a pyro solver over time. Anyways, the goal of my se...

Hi guys, I'm really struggling with what seems to be a rather easy setup: Covering a collider object in smoke and at some point suck in all the smoke through various holes. Negative divergence seemed the way to go however it's completely ignoring the collision (see attached flipbooks)...

Hi, I'm trying to understand how the divergence field works in Houdini, and how it interacts with FLIP fluid particles. Positive divergence should cause the fluid to expand but there seems to be a difference between having positive values in the divergence field and having positive values of div...

Hi, what is a plausible way to reverse the divergence of particles? The classic example, a glass champagne. After a period of n frames the divergence have to stop cause my wife hate stains on the floor.. ;-) . A Particlesystem is filling the glass. I realiced the foam with popgroup...

Hello fellow magicians, I'm trying to better understand gasequalizevolume DOP inside FLIP Fluids and so far I haven't found anything usefull outside of the Houdini documentation and example files. So I tried to create a simple example file to test it out. So far, I can't seem to create one of...

I was trying to expand the some smoke simulation using divergence field. the divergence field create a big hole in the smoke simulation. any idea why is this happening Test Smoke.hiplc.thumb.png.266f86a3ef124d96c5eba050f34c9d5b.png)

Greetings, I'm currently working on a large scale FLIP animation and I'm running into a question, I need to fill with liquid a very large object (like a house), and I figure that the divergence was doing a great fob until I reduce my particle separation for a higher definition. Sim...

Hi Guys. I'm trying to create a kind of 'expanding foam' effect (like an Elephant's Toothpaste chemical reaction). Expanding out of a teacup. But my FLIP fluid is hitting a weird shelf and not overflowing the edges of the cup properly (see below). My emitter is a sphere at the bottom of the cup...

Hey guys, I'm trying to use divergence with flip but things get kinda unstable. I'm using only the point attribute, should I use a volume field as well somehow? Thx FLIP_Divergence_v0100.hip

Hi, I search and read a lot of post on google/ODForce without really finding a answer to that. I trying to see how I can compress a fluid correctly. Just to illustrate one case from many others , I try to compress gas with a piston in to a cylinder. I know Houdini is more a artistic tool than a...

Hi Guys, I am currently working on a shot where I need to simulate an object falling slowly through deep water whilst bleeding (The more blood the better). Initially I began with a pretty simple setup, An emissive object, a collision object and a divergence volume which is being used for...

Hey folks, Does anybody know how to use the "Goal Divergence" and the "Pressure" in the "Gas Project Non Divergent"? Whenever I try to inject a field the particles go crazy. Would be nice to get something like a explanation or example file. Thanks
