Vortex woes

[insertmesh]

Unfortunately I couldn´t use tyVortex as a force in Phoenix

I ran into the same issue myself recently, and implemented a Spacewarp wrapper for tyFlow helper forces, that allow you to input them into PhoenixFD.

haha, thats why we love you. You keep fixing things that bug all of us...

Its for my personal short though, so I´m not in a hurry. Just getting knots in my brain again...
Actually I figured out how to solve part of my problem: I had tried to break up the uniformity of the tyVortex by changing the Multiplier of the velocity Affect in the force op. Once I dialed that back to zero and put vortex and pull force at the same value, it stopped randomly expanding.

I´m still wondering where those "dead" particles come from though, if its missing velocities in the phoenix grid or the way tyFlow interpolates those velocities between grid voxels.
The resolution of the phoenix sim I used to influence the tyFlow particle was relatively low (just around 10 mill voxels), so maybe there is the culprit?

Deleting the "dead" particles is probably a better idea for now than what I´m doing.
Now I´m sending them to a new event with extra forces, but then I have to retime or slow them down them separately as well, as they don´t follow the phoenix retimed sim anymore in that event...

I´ll see that I can step back to my previous attempt and make a preview of the issue.
