It's been hard getting support from the Houdini community on this topic. I'm not sure if the solution to my problem is obvious, or if it's too much of a headache to explain the solution. Either way, this forum is my last hope. I'm trying to simulate a small scale breach—think head coming out of a tub of water. Right now I'm in the RND stage, so I have a simple flat tank setup with a colliding sphere that has an animated mountain noise. Everything is stable when running the sim on a single machine, but when I slice it up and send it to the farm I start to experience volume loss in the tank. I'm assuming it has something to do with the particles being transferred between computers and in turn the attributes become unstable, this is just a guess though. If this is the cause, I wouldn't know how to fix it since my knowledge on distributed sims is limited. The screenshots I've attached show the difference between running the sim on the farm vs a single machine. I only ran the sim to frame 14 in order to get quick results. The actual flip object and solver parameters have not changed between each screenshot, the only difference is whether it's distributed or not. Screenshot 01: Distributed Simulation Screenshot 02: Non Distributed Simulation ALSO, when watching the masterclass on setting up the distributed simulations for FLIP, I noticed that the "Create Boundary Layer" option is manually disabled. I've followed this in my workflow, but technically I need my tank to behave as if it were "infinite", so should I keep this on? Maybe not. Either way I ran a test with it enabled just to see what happens. I don't normally work with tanks when using FLIP so this is a learning experience as well. My results are shown in the screenshot below. You can see that the padding doesn't sink, which makes sense I guess... but the active simulation still sinks. Screenshot 03: Distributed Sim with Boundary Layer enabled Screenshot 04: Distributed Sim with Boundary Later enabled - top view This was probably too much info, but I'm trying to be thorough in order to pin point the issue. I can provide the .hip file as well for those who want it. Any help/insight is appreciated. I'm open to any tips and tricks as well, thanks!

Hey guys! I am doing a FLIP simulation using a moving Flat Tank with Narrowband and I am getting this weird banding/little waves in the new generated particles in the boundaries. Some one have a solution for that problem? I am tying all day without success :C

Hi ! I am a beginner. Houdini crash when I try to work with fluids. I just created a flat tank, and just to look at the differents nodes, I cliked on the node fluid_compress1 in the fliptank_fluid and a get the "1460: Fatal error: Segmentation fault Saving application data to C:/Temp/houdini_temp/crash.splashdown_01.alice_1460.hipnc" The last time the fatal error occured when I changed the particules separation to set 3. Before I had other fatal errors in differents operations but always with fluids. A friend built my computer recently, maybe there is something wrong with it. I didn't have any problem like this with bellowy smoke tutorial or procedural ground before. Could you help me please ? I have attached my computer config. Thank you !

Hi every one. Is there a way to get any other shape of flip tank? I can just simulate it in the tube and give it a time to settle, but it would be easier if there is an option to make tank cylindrical. Thanks. Tom

What I am trying to do is to get a fluid of any kind (pop or flip presumably) to interact with the fluid in a flat fliptank. Seems like it should be easy, but I can't seem to get them to react and mix like fluids (or interact at all actually). More detail: I actually am trying to get a cloud of blood to spread out into a pool under a body that has just fallen in. Perhaps this means I need a different solution than if I was dumping particles into the tank from an emitter outside of it, but I can't even get that to interact, so any advice on this would be most helpful, and I am grateful to anyone who spares even a moment to consider the problem. Much appreciated! PS- I have scoured the internet, including this site, for advice on this, and have come up empty handed.

Hey guys, is there a way to use NB on standard liquid object (like a sphere)? I need to melt something and the simulation is getting very expensive, it would be awesome to use narrow band on it but I could only use it on a FLIP Tank by now Thx, Alvaro

Hi, I am running a boat simulation with regular flip tank, i am trying to figure out how to track the flip tank to the boat... After some quick search it seems that i have to use a FLAT tank or a tank that came with ocean suite Is there a way to keep may flip tank and make it follow may boat? Thanx

is there any way to control Ocean surface that it can generate waves only at its last part like we see in real ocean (overall calm but waves in the end)
