i did a small simulation to work with liquids inside Houdini, is just a emitter that hit 6 cylinders and fill the tank,

my basics with liquids simulations is with real flow, i want to know how can i change the size of each particle, if you see the video each particle is a huge ball, can i reduce the size?

i also wanted more resolution on the liquid, but i allready check that with the “help” in particle spacing .

also do you have another tip to make it look even better? thanks, .
i might need to use a higher sub steps for collision, i use 15 (defaults is 25) but the cylinders pass the tank.

I'm somewhat inexperienced with particle fluids, so I can't help you with all of this, but I think I can help with particle size.
In the DOP network there is a Particle Fluid Object node most likely called “particlefluidobject1” Click it and check its parameters, one of the parameteres should be “Particle Separation”. Lower this value just a tiny bit, perhaps to 0.08 or 0.07, and see what you get. The lower the value, the smaller the particles.

heydabop thanks i will check that i read in the help that was for the resolution, this is what i am getting in my test, this is a little video, i cooked last night the simulation.

and it was particle separation was set to .01

Hm, well it looks like that at some point your simulation “explodes”. So perhaps you should up your maximum substeps to preserve accuracy, or go into your fluid solver node and under advanced choose a different simulation method such as Runge-Kutta 3(2) or Runge-Kutta-Fehlberg, which I think are more accurate than Runge-Kutta 2(1).

i will try all of them, don't know why “ explotes” in the middle of the simulation.

in real flow you can set exactly how many particles per 1m cubic
and at the time to build the mesh how thin or thick you want it,
and with that you can set fewer particles and trick the mesh and get the same result.
i am still not sure how to achieve this in Houdini . still doing some tests.

Hey, i think i found what i was looking for,
if you go to the particle emitter, the actual geometry there will be a dop import, witch bring the simulation to it, and below will be a particle fluid surface, if you check the parameters, there is a “point radius scale” parameter, i will be playing with this one, i will post some stuff later on .

Alright, I hope you get it working.

another test.

a little more separation between the particles so it cook faster, and lower the liquid shader.

Hello, I am brand new to the community and think this looks pretty good. It appears that the liquid is moving fairly well and was wondering if you would share the coding you used.

Thanks for sharing and best regards

That looks much better. My only other advice would be perhaps making the collision mesh more complex so that the fluid can get closer to it. But overall, excellent job.
