Advect particles with a dynamic object

[Mark01 5]

Hey everyone!

I am try to simply advect particles with a moving object.

We have particles/grains floating around and a person runs through them at speed so I just need to create some advection/turbulence, more than what's already created from the collision. 

I assume it is as simple as pyro but I can't seem to work this one out. Any ideas?

 

Thanks

yes, simple pyro, save your vel field to disk and create a separate dopnet with a popsim and add an AdvectByVolume DOP node
There is an example in the docs https://www.sidefx.com/docs/houdini/examples/nodes/dop/popadvectbyvolumes/AdvectByVolume.html

I'm not sure if this is what I am looking for.

Im looking for the object to just disturb the floating particles slightly.

 

Any other suggestions?

 

Thank you!!

You need to create a smoke sim first, then advect your particles with AdvectByVolume
and no need to post the same question twice, thanks

I'm just thinking for pyro, it's simply a case of plugging a vdv in a fluid source. 

So is there not a more simple method for particles?
