Bond fluctuation model
The BFM (bond fluctuation model or bond fluctuation method) is a lattice model for simulating the conformation and dynamics of polymer systems. There are two versions of the BFM used: The earlier version was first introduced by I. Carmesin and Kurt Kremer in 1988, and the later version by J. Scott Shaffer in … See more Carmesin and Kremer version In this model the monomers are represented by cubes on a regular cubic lattice with each cube occupying eight lattice positions. Each lattice position can only be occupied … See more 1. Four lattice sites next to monomer m in the direction d are empty. 2. The move does not lead to bonds that are not contained in the bond vector set. See more If the move leads to an energetic difference $${\displaystyle \Delta U}$$ for example due to an electric field or an adsorbing force to the walls. In this case a Metropolis algorithm is … See more In both versions of the BFM, a single attempt to move one monomer consists of the following steps which are standard for Monte Carlo methods: 1. Select … See more 1. The lattice site to which the chosen monomer is going to be moved is empty. 2. The move does not lead to bonds that are not contained in the bond vector set. 3. The move does not lead to overlapping of bond midpoints.
