creating an absorbing boundary

Hi all,

I am simulating a system of particles(two types) interacting via lj potential. I want to create an absorbing boundary for a Brownian particle(say type 1). The particle should be removed from the system when it reaches the plane for first time. How do i do that?

Thank you

Off the top of my head, you might be able to utilize these two as a starting point.
