1st issue - a stable vortexField

i have a particle swarm of 50.000 with random radii. a a turbulenceField has been applied to create pattern. the initial state is now set to a dense ball-like particle cloud. the emitter was deleted. so, the particle count is a 50k, live forever and no new particles will be created. this is my start scene.

now I´d like to create some spiral shape to the particles. the problem is: vortexField(Y) blows all particles into universe. so I´d need some stablizing field or modifiy the vortexField in that way so the particles stay together and only receive a spiraling movement. my goal would be to create spiral arms but the particles don´t step outside my XZ-boundingbox. how would I start..?

any input is much appreciated. here´s the scene if anyone is interested. it´s maya2008. hope it´s not too big.

... it was, but I hope you get the idea from my description.

everything starts and ends in the right place at the right time.

I had success with a radialField with negativ value sucking everything now into 000. the tricky part tho was to animate magnitude now from vortexField and RadialField to keep a balanced state between these 2 forces.

but it looks too regular still. I´ll try with another Turbulence field to define some character.

after some tweaking. 100k particles right now. I think it needs some nebular added. updates will continue.

here´s a picture from early state. working with particles is fun! but I think I have to spend some more time with maya dynamics.

Probably a bit late now but you could try a volume axis field, that has turbulence, vortes and uniform effects and would only effect particles inside its volume.
