thanks guys, I got it working already. I just needed to adjust the control range on the disturbance node.

oh, can't you just set the pulse duration to 0? Try the same thing with fluid source node. hit use noise. You will see it start to move. Set pulse duration to 0 and it stops completely.

Here is something that might help. Create a temperature field (or create a scalar field). Make it so the temperature field (or scalar field) dissipates. Set the temperature field (or scalar field) to be the control field of the turbulence. Set control influence to 1. If you are using temperature make sure to turn off buoyancy. After the temperature or your scalar field dissipates the turbulence will stop. That way there will always be more turbulence near the source and it will fade off.

one more : ) gas match field and analysis to create scalar field getting length of velocity. Use that as control field for disturbance and turbulence. that + what I did above gives this: https://drive.google.com/open?id=13dfeWw2tefsNJ-NSSWJo9w3M9wQHsUEZ

still working on a good solution, but here is something else that I tried that works a bit better. I added gas vortex confinement,but kept the values low (around 1 - 2). I plugged that into a gas repeat solver. That seems to work much better than using confinement and turning up the scale. Also added more sub steps on the dopnet. That seems to just create a lot of small swirl. This isn't perfect buts its getting away from disturbance patterns https://drive.google.com/file/d/1UNp13Arv7sv7XiWhF82A5OTH_CWhTME1/view?usp=sharing

You can manually open mplay on the screen you want then hit render > listen for renders

You can also hit disconnect at the top right. Next flip books will open a new mplay.

I meant upload one frame as a vdb file or bgeo.sc so I could see if I could fix the problem. Or post file, which ever is easiest.

isn't that just because the control field is temp by default, which dissipates? I switched the control field to velocity. I am still confused how to get this to work. I create a mask of areas with velocity, but in turn, the turbulence affects the very mask its using causing the turbulence to never stop.

@heydeun2 is there anyway you could post like a frame as a vdb or something?

I guess I'll keep updating my progress, here is where i am at now: I still have that pattern tho : ( https://drive.google.com/file/d/15Ow6igaLXkfRdotvpJkyNBvLtNO4qc29/view?usp=sharing

so I am slowly solving this : ) part of my trouble is I was using a gas wind. Using a fan force affecting only part of the velocity allows for better swirls. I still wish there was a better way to control swirl tho

I dont understand how you get such nice movement with pyro using disturbance or turbulence. I have tried all the micro solvers and they produce weird results too. Obviously I exaggerated the motion,but you can see none of them really seem to create a swirling motion like maya fluids. First photo is the patter disturbance creates, the second is turbulence and third is gas vortex equalizer. It seems easy (sometimes) to tell what software was used to create a simulation based off its look. Maya fluids has its look, fume has its look and now I notice pyros look. Look at all these sims, they don't have swirling motion like maya fluids, they have turbulent patterns instead. Either that or really small swirl from gas confinement. take a look at this album, you can tell what I am talking about by the pattern seen in these simulations. https://vimeo.com/album/5305665 It seems really hard to get motion like this: https://vimeo.com/141476011 only using disturbance any turbulance.

I mentioned in my first post I didnt like the results from pop steer seek : ( thanks though

I had to re-upload, I realized I accidentally did the pscale in dops so the collision isnt right. I just made a new attribute scale in dops, then set pscale to = scale after dops : ) let me know if that helps PArticles4.hip
