Lately I have been learning the flip solver. I am concerned with one big difference with the pyro/vellum solver, which is that i could not reproduce what the flip solver does with a dop. The inside of the this solver is much more complex. I feel a bit insecure about this, I don't like being unable to reproduce what I learn here in a custom setup ( which I might need to do if I have to do a more custom simulation, with interactions with others solvers or whatever) and I don't like having a sim that automatically looks good but that i cannot fully control. How did you implement it in you workflows ? I guess you can customize a lot by editing fields before inputing them in the flip solver but would that be enough ? If anyone has advice it would be great but I would be glad as well to just hear your opinions or your experience with this change.

Hi there! I'm still new to houdini and I'm having a lot of trouble on a project and was wondering if I could have some help or at least some direction on how I could achieve this effect. The project is to simulate a pool of lipstick with a rotating animated object in the center. To resemble the lipstick viscosity I wanted to make a very dense fluid/particle sim, with some clumps of even denser material. Here's the best reference I could find for the effect https://youtu.be/zBGgfPXwLMQ?t=165 . I tried to make a Flip sim with high viscosity and create a viscosity map with a noise sop for those extra viscous chunks, but I couldn't make clumps like I wanted to. I don't even know if the Flip solver is the best tool for the job, but I couldn't think of anything that would get me closer to what I wanted. I also tried to create a few pieces of RBD objects in the middle of the pool, but it didn't work at all. I just really have no idea if I'm on the right direction. I'll add the hip file aswell as a flipbook of the meshed sim. I am using 18.5 by the way. Any help or direction is appreciated. Thank you! lipsticktest.mp4 LipstickPool.hiplc

Hello there! I'm trying to create a ship sailing effect on Houdini 17.5 (with Guided Ocean Layer tool). But I'm having lot of issue. - First of all, as you can see on flipbook, I have lot of particles popping up from ship sides. Why it happens? Can't figure out how avoid this problem. - I used the Deforming Object shelf tool for simulating the ship as volume source. However if I choose Volume as Velocity Type on Flip Solver > Volume Motion > Collisions tab, it looks like fluid doesn't interact well with my geo. Basically I have not splashes, even if I select "Use Volume Velocity for Collision" on Flip Object > Collisions. So I need to switch on Point velocity Type in order for me to have good results. Is that a correct way even if my collision source is a Volume? Is it better to treat collision geometry as volume or mesh? - Is there a way to avoid splashes to slide on surface? I tried to increase the Velocity Blend (on Flip Solver > Particles Motion > Droplets) with no results. - Lastly, I'd like to achieve a good results regarding wave trails (see pictures). Basically I have too rounded and large waves from the ship prow. I'd live to have more V Shaped waves. My scene is more or less in real scale (meters). I used a 0.8 Time Scale value in FLIP Solver in order for me to have good trails, but cannot achieve the desired result. Any help will be really appreciated. Thank you so much for your time.

I want to make water from the hose. Like a fire truck, very strong and fast. I tried to use a popslover, but it didn't look goodon the colision side and it didn't speed up properly when I tried to use flip Solver. I tried to bring the location and speed of the particle to flip Solver but it didn't work. What should I do? I'd appreciate it if you could help me. thank you -
Hello there, I'm making a classic Ship Sailing Effects (ocean guided). I'd like to add a custom velocity to the bow of the ship in order for me to have a good turbolence like this: Through a Volume VOP (please see the hip attached) I created the following velocity: The shape I had it's what I want (straight velocity to the front and curved ones along the sides of the ship, so they can push the water for having a classic V shape). However, I'd like to invert the value of it: having higher velocity in the center e gradually less on the side. With my solution I have to much velocity on the side and less on the center of the bow. Basically I need the trails to be red (high) at Z=0 and blue (low) at the Max Z bbox. Furthermore, is my solution right? I blast a part of the bow, scattered it and then use a Volume Rasterize Attributes for creating the velocity. And, lastly, what kind of operation do I need to use in DOP in Volume Source? Somebody says "Add", somebody "Pull". What is the correct way? I hope you can help me. Any suggestion will be really appreciated. Ship_Body.obj Ship_Custom_Velocity.hipnc

I'm trying to add foam in the first frame of my simulation. I'm using a scatter node to distribute the foam in the first frame,My idea is to inject these dots into the whitewater solver so that they are calculated dynamically. I want to do something like this https://vimeo.com/162173918. Try to make an object merge of the dots on the Whitewater source node but I can't make these dots become foam particles thanks !
