protein diffuses to boundary..

Date: Wed Mar 07 2007 - 16:21:24 CST

Hi All,
    I have this problem where my protein is diffusing to wall of my spherical boundary. Diffusing in the sense that after a few nanoseconds,all of it drifts towards the solvent spherical boundary. I guess one solution to avoid this is to make big sphere or conduct simulation in a periodic box. But i want to know some solution presently for spherical boundaries so that it does not drift and interact with my spherical boundary or say walls.

 Thanks in advance for any help.
