Variable gravitational field

Submitted by nicolas.aalderete on Sat, 07/23/2016 - 02:20

Hi,

I was wondering if it is possible to apply/modify the gravitational field to particles after they cross a certain spatial coordinate. Based on what i have seen this could be done by creating groups of particles after they enter a certain region, but i can't seem to make it work.

Any thoughts on this?

Thanks,
Nicolas
