particles streaming around object

[tycera]

I'm looking for the best way to have particles stream smoothly round an object like the animation from around 1:23 here ..

It's not exactly collision, and I haven't been able to get it close enough using forces either.
Anybody got any ideas?

Thanks

You can try surface force operator, and apply some negative values (so it repel particles from surfaces, instead of attracting to them)

Thanks.

It took a bit of trial and error, but the "Follow" force settings are giving me close to what I want. I'm going to create some meshes the same shape as the trajectory I'm aiming for to see if I can't do it a little more accurately.
