A method for lamping atoms into particles in particle dynamic method

Generalized particle dynamics method (GP) is a kind of new multi-scale analysis approach which relates various scales naturally through cohering small scale lattice to large-scale lattice. in this paper, a method named nearby condensation method is proposed to lump small scale lattice to large-scale lattice keeping topology structure and mass distribution. The method provides a theoretical support to the GP method. It is indicated that, after cohesion BCC (Body-Centered Cubic) crystal structure possessed the same topological structure and mass distribution, and FCC (Face-centered cubic) crystal structure possessed the same topological structure, but the mass distribution gradually converges to a steady state.
