  1. FLIP / FEM - Mutual Interaction

    Sup guys, I'm trying to make a Fluid pushing a FEM sphere. I've found some information about fluid force + some setting on the flip solver but the FEM object just don't move. I'm clearly doing something wrong. Can anyone help understand what's going on? Thank's, Alvaro FLIP FEM.rar
  2. Cloth + RBD Interaction - Is it possible?

    Hello guys, I have this simple scene with a cloth (grid) pinned on all 4 corners and i'm trying to make it interact with an RBD Sphere. Can anyone give me a tip on how to achieve it? Right now the sphere is just passing through the cloth. Thx in advance. Alvaro
  3. Hey everyone, I've been working in Houdini for some months now but I'm still not as fluent as I'd like to be. Mainly I've been working with different types of fluid behaviors, RBD, shattering with voronoi, etc. For the last month I've been learning VEX and VOPS. Although I don't know how I should approach this project. I need to create a bubble bath effect which interacts with a character for proof of concept. I was thinking of creating a filler object inside the tub, use it to scatter points, copy spheres and randomize the size, then create a POP network to play with the motion of the bubbles. This method just seems way to simple for the complexity that is Houdini haha, I'm also not sure if it would work. I attached some pics of what I'm looking for, but any advice would be greatly appreciated!
  4. flipfluidobject Interaction Question

    Hi there. I've been searching for the answer for this for a while and I can't seem to find a concrete answer. Well, as the topic says I have two (or more) flipfluidobjects in a DOP network but I need to be able to: 1. Have them interact with each other 2. Be able to assign different shaders to them. When I merge everything into a single flipfluidobject and surface it, I can't figure out a way to mask one from the other. Sorry if this is a very basic question, but I'm at the end of my rope Obviously new to Houdini.
  5. FLIP/Grains interaction setup - hip file

    Hello All, Been lurking for a bit since I started dabbling in Houdini, and must say am in awe of the level of genius on exhibit here! Houdini is still kicking my ass in so many ways, but I'm a glutton for punishment I guess, and looking for excuses to spend less time in Max. This is a simple setup that seems to work OK, but I'm curious if there are other/better ways of getting these 2 solvers to interact. Currently I'm using PopAdvectByVolumes on the Grains to transfer Vel from the FLIP sim, and building a collision SDF in a SOP solver attached to the Grains sim which then gets pulled into a SourceVolume on the FLIP sim. I'm sure this is nowhere near physically accurate, but it does look pretty neat, and can be improved by adding custom attributes on the grain points for wetness etc. Thoughts? --Dave DJS_ODForce_FLIP_Grains_Interact_SampleSetup.hip
  6. FLIP with Bullet Interaction

    I'm trying to create a effect where I have objects inside of liquid. The FLIP simulation alone looks nice but after adding around 50 Bullet sphere's to the sim the result is lot worse. Feedback scale is set to one and reseeding is turned off. Overall the interaction between Bullet and FLIP seems to be working fine but it feels that the liquid is losing some of the volume. Point count doesn't change tho. I tried both packed prims and usual geometry for Bullet and I am using usual geometry at the moment because I got better results with it. Any thoughts on how to keep the volume of the liquid same? Oh and Houdini I'm running is 14.0.201.13. Cheers!
