The method automatically cope with the interactions between the particle and the channel walls. We apply the method in a study of particles moving in a channel with obstacles of different shapes. The generality of the method also makes it applicable for simulations of motion of particles under influence of external forces.7 pages, 2 postscript figuresFluid DynamicsComputational Physicstext
