Stones on conveyors and vibrating screens - hkroeber - 04-20-2023
Hi
most of the time i am working with different sized stones on conveyors on vibrating screens. in different situtations i tried to use particle physics instead of physX but there are a lot of restrictions that have always took me back to the hardcore physx way. Last time it took 2 days to cache a solution. In normal projectsituation this is too long. the customer wants always more finematerial (sand).
Look the attachment to see what i mean....
Anybody here to give some tips on how to speed up those things?
Regards

Check out the upress official sample file.
It's basically Low res sim using PhysX, and then it's upressed in the second TyFlow.
Here is a good example on how it looks:

Thanks for the tip..
i think i've seen this procedure but never tried it. In my situtation it will be not that simple because the bigger stones still have to be there but i give it a try.

You can pretty easily separate percentage with split operator (in the second Tyflow) on whatever amount of particles you don't want further brake, and just connect it to an event with Flow update operator.
OR..
In your main flow create separate PhysX flow for larger chunks, and then you will get 2 flows within same flow (small and larger chunks)
Now add a Particle groups operator to each of them. Make "A" for particles that you want further brake, and make "B" for larger chunks.
When you creating Simple reference Flow, you can then call whatever particles you want if you select A or B in both operators (Birth Flow, Flow update).
