data usage

[Fragster]

Hello,

I'm simulating some dust elements with Phoenix 2.2.0 Revision: 24510 on 3ds max 2015.
The sim is based on pflow emitter and everything worked fine so far.
Now I have run the sim on higher settings (100 million cells) to get more detail and for some silly reason (probably my own stupidity) the pflow emitter node was shut off.
You can imagine how happy I was when I came to the office today and had to find that the emitter was off and the simulator was empty, of course.

Whereas nevertheless large cache files were created.
So I was just wondering, since this data is written, it should be displayed in the viewport, right?
Is this data usable for anything (except hard disk clutter)?


Best,
Marck

If the caches are large despite nothing visible, there must be something that causes movement in the simulator. We have a system that checks whether any objects interacted with the simulator and if not, the simulation quickly jumps forward to the next frame and so on until the end. If you have exported velocity in your caches, you can check it in the viewport preview if there's really anything going on. In case the velocity looks just like you wanted it, but without any smoke, you may try to resimulate using it as base cache and with no resolution increase or wavelet or time-bend. This will only work in case you were emitting smoke without temperature - if you have any, you have to start the simulation form the begining - the high temperature rises up and alters the velocities.
