Hi all,
I have created a particle system with 3 particle types, green, red and yellow.
I need:
1)Green to attract road SOP
2)Red to attract villages SOP
3)Yellow to fill up the remaining container evenly
4)Reach equilibrium in the container
But no idea why the attractors are not attracting, so i used follow, but once the particle systems are collected, the follow effect is gone. HELP! If possible, I also need the 3 particle types to have a different effect radius, in decreasing size (G, R, Y) so that when a voronoid fracture node is added, they are of different sizes.
Thanks in advance!

i have attached the file i was working on, the problem is the particles doesn't stop moving.
@pclaes> i was referring to two different particles systems, in pops. i was hoping to produce an effect where the yellow particles would repel one another equally, while the green one would repel the others at a larger distance, but they will all spread into the nooks and crannies of the container and eventually settle down.
i guess i was referring to the effect radius when i said “charges”? like how a positively charged particle would repel a negatively charged one, but referring to the distance of the attraction/ rejection.
@soothsayer> yes, something like the video, but on a flat plane instead of three dimensional. what is a “custom solver setup”?
thanks all!
EDIT: sorry I left out the file! have attached it now

Hello,
I have a system of two different particles interacting in a container, I want them to interact until they reach an equilibrium based on their charges and the area of the container, any idea how I should set the charges to create this scenario?
Thanks!

Hi again Dinkleberry,
I just looked at the stunning amounts of manually added points in the group nodes… thank you for putting in so much effort! I have added several nodes with patterns in them, so as to prevent exhaustive listing and automatic update regardless the geometry, perhaps you could find it useful for your geometry in the future.
Attached is the updated file.
Cheers

Hi Dinkleberry,
The file works perfectly, I had forgotten entirely about the much-maligned cookie node. Thanks so much for your help, it really solves many problems!

Ahh I see! Thanks so much for your help Jeff! The grouping before putting it into the popnet was exactly what it needed! )))

Hi there
I was wondering if anyone can help me with this: I need to surfsect this wobbly surface to create floors for towers, but I keep missing portions of floors.
Any ideas on how to get complete cross sections?
Thanks in advance!
Attached is the zip with the bgeo and the hip.

Ah thanks for your help Jeff, I have found out that the particles can be sorted into different groups in the popnet, although they must be listed by number, and in a linear string. It seems to be giving the correct simulation, although this listing method seems to be exhaustive.

Hi Jeff,
Thanks for the reply, The POP network works fine with a single type of particle (as it is now), but what I'm trying to do now is to add another set of negatively charged particles into the mix, so that the simulation runs two groups of particles against each other.
I'm not too sure where to programme this second set of particles; in the same popnet? or elsewhere?

Hi there,
I have this particle system where particles bounce around and achieve equilibrium, but I need to have different types of particles with opposite charges/properties interacting.
I have tried having two sources in the popnet but the final output refuses to interact. (please ignore the voronoi sop). I have also tried having two separate popnets but that failed as well.
Thanks in advance!
Please play file to see particle simulation.

I apologise, I forgot to mention that the video is in the 2 MB zip file attached, as the forum doesn't allow for wmv files.

Hi there,
I have been trying to get my particle systems to work like in the video below, but cannot do it. Do you have any idea how to achieve this effect?
I need the particles to bounce off each other and eventually achieve stability.
Thanks in advance!
