Attractive forces and wall sticking for particles.
 
I am trying to make a system where particles flow through and get attracted to some surface. When these particles get close enough, they will interact and stick. Is there anyone out there that knows how to incorporate these forces. Any help at all would be appreciated.

Hi,
I have a suggestion, you can do that by implementation of a body force to your particles via a UDF. you can define your desired force as a function of distance between your surface and particles.
another way also is to use thermophoresis option in DPM panel, if you can get your desired force by that with some tricks!
