Had fun doing it. Hope it proves useful to someone Cheers ! Edited September 9, 2015 by gaurav 10 Quote Link to comment Share on other sites More sharing options...

Atom Posted September 3, 2015 Share Posted September 3, 2015 @guarav: Thanks for the tutorial, I tried to complete the setup but mine does not work like yours. I am using Houdini H14. Can someone take a look at my file and tell me what I did wrong? ap_contained_FLIP_fluid.hipnc Quote Link to comment Share on other sites More sharing options...
gaurav Posted September 7, 2015 Author Share Posted September 7, 2015 You are welcome @guarav: Thanks for the tutorial, I tried to complete the setup but mine does not work like yours. I am using Houdini H14. Can someone take a look at my file and tell me what I did wrong? Try increasing particle radius scale. .05 is too low i believe defaults is > 1. Cheers!

Atom Posted September 8, 2015 Share Posted September 8, 2015 (edited) Thanks for the tip. I did increase the particle radius and that makes the particles larger but I still do not get any 'sloshing' action out of this rig. I notice some kind of parenting trickery happens very quickly near the end of the video. Just to clarify do I bake my sim with fetch_sim as the child of source or do I bake then parent? Can someone post their working version of this effect as a HIP file perhaps..? Edited September 8, 2015 by Atom Quote Link to comment Share on other sites More sharing options...

Atom Posted September 10, 2015 Share Posted September 10, 2015 (edited) Thanks for the HIP file, that works! Next question, how would I render this? I have tried adding a camera and lights but the image is always blank. . . . Ah, now I see. The out/liquid ROP you have already setup.

Atom Posted September 11, 2015 Share Posted September 11, 2015 (edited) One more question. I swapped the cube with a sphere and it does not work. The fluid looks great on frame #1 but then it dissapates and is gone completely by frame #7. How do I use this system with other shapes? I am attaching my file if anyone has time to take a look. ap_contained_FLIP_fluid_1b.hipnc Edited September 11, 2015 by Atom Quote Link to comment Share on other sites More sharing options...
Atom Posted November 9, 2015 Share Posted November 9, 2015 I think the problem I am having with this technique is that it only works with a cube. The volume is cube in nature and when you try shapes other than a cube the FlipSolver 'kill outside volume limits' removes particles that do not fall within the cube. So a non-cube based shape simply leaks all the fluid out as time passes. I would still like to know if there is a way to use a shape other than a cube, for instance hollow font characters.

paulh Posted December 7, 2015 Share Posted December 7, 2015 Hey Atom, I see now that your post is from a while ago so maybe you've got it figured out... If you add a slight negative Offset to your isooffset node (or use Ray Intersect mode) and increase your FLIP volume limit it should work with your sphere. I think the problem I am having with this technique is that it only works with a cube.

Atom Posted December 14, 2015 Share Posted December 14, 2015 Thanks Paul, I never did figure that one out so it helps to have a solution. My original intent was to try self-contained fluid inside iconic shapes such as test tubes, wine glass or other typical graphic design elements that might be fluid containers.
