I am trying to achieve the effect of having a solid piece of geometry sitting as a fluid, being brought in by either volume source of pop source. This initial piece just has fluid ripples. The second part is I have emitters in the same dop network that are there to create a dripping effect. So it looks like this liquid that is holding shape is dripping. The problem is that I cant seem to create independent surface tension for the two separate sources. If I increase the surface tension to what I need then the main piece of geometry gets washed out. I have been looking for a solution to this but nothing comes up for Houdini 18

I am working on a shot where a very viscous fluid hits a character. Everything is working great on the sim and giving me look I need, but I was wondering if I could add a "stretch limit" to it somehow. Like "if it stretches by x amount, break it up into smaller pieces" without losing the viscosity much or getting it back after the breakup. I am not sure what attribute I could reference for that (if there is one). Help me odforce, you're my only hope.

hey houdini users, i'm doing a flip simulation for strawberry falling into chocolate but i cant figure out the right surface tension for viscous fluid and i don't know how houdini calculate Surface Tension or how to find the relation between liquid mass-density and surface tension ? and also does houdini calculate it in millinewton per meter ?

HI Did anyone know how to use those .cpp .h file? in vs always warring somehow...and i also want to put those scriot into houdini mayabe need translate to vex did anyone done this before？ Thankyou! SPH.zip

Hi Guys, I'd like to know a way to control different forces, based on some attributes. I find is very easy to control Pop Forces based on position or velocity or Cd attributes... but I want to have this control using for example Gas Turbulence or Gas Surface Tension to control my fluid... Imagine I have one liquid that is flowing along a curve and after TX > 5 it will increase surface tension and turbulence. How would you do that?

Hey Folks, I recently heard about Yannik F.'s Q-Solver Plugin for Realflow (275$) which looks really promising for small-scale liquid-simulations (good surface tension, sheeting, etc.) In my opinion even better than some custom fusionCIS stuff). What do you guy's think about it? (There's a lot more RnD stuff on Yannik F's Vimeo-channel) Annother Example: Release-Notes: https://www.youtube.com/watch?v=5Ud8qBa35r8 I'm (still) wondering if something like this is possible in Houdini. I know that Alejandro Echeverry is working on some similar stuff (http://forums.odforce.net/topic/18111-flip-smorganicsheeter-effect/) , but his tool is to my knowledge not yet finished and available for public use. Is there something similar in H? I did some small-scale stuff a few weeks ago, it turned out ok, but the results couldn't get close to the q-solver stuff - even with a surface tension microsolver attatched to my flip-solver. Some the discussion regarding my project and the topic can be found here: http://forums.odforce.net/topic/22272-how-to-emit-additional-small-droplets-from-a-water-drop-crown-splash/. I'm courious what you think!

This is a WIP of what I've been doing on my spare time. Hope you like it! Comments and Critics most welcome
