Up res simulation form particle sim

[morzh]

I've made a particle simulation, then created 3 fields: density, vel & rest. Using Gas Particle To Field DOP i've copied the density and velocity to the respective fields. Now i want to upres my object, containing 3 fields. But it doesn't work. THE QUESTION IS: what I'm doing wrong ?

didn't look at your file yet but here are a few hints :

1 - the upres process doesn't take the density of the lowres sim, it takes the lowres source.

2 - the velocity needs to be copied onto lowresvel. vel is the upres velocity field.

3 - your velocity needs to be extrapolated outside the particles or you'll get stuck density

4 - why would you use particles as a lowres fluid sim in the first place ?

1. I guess it is fixable... i'll try to correct it

2. I have that idea in my mind ))), but i do not implement it

3. So velocity should not be zero at all in any voxel ?

4. It's interesting for me to build some "non standart" setups to deeply understand the possibilities of the instruments. (i guess i've understood your question)

So to upres the fluid sim i need the source of the density & lowres velocity. And what about the rest field ? It simply contains vectors pointing outwards from the center of the fluid container ?
