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.

The local fluctuation of the bonding creates a field of forces to move the ions, which in turn, triggers new bond fluctuations.

WebOct 13, 2024 · The model protein has a single sticker that may reversibly dimerise and elongate into semi-flexible linear chains. The growth is hampered by excluded-volume interactions that are encoded by the hydrophilic spacers but are rendered cooperative by the attractive interactions of hydrophobic spacers. http://www.sklogwiki.org/SklogWiki/index.php/Bond_fluctuation_model WebOct 1, 1995 · Elastic behaviors of single polymer chains adsorbed on the attractive surface are first investigated using Monte Carlo simulation method based on the bond fluctuation model, and it is found that elastic force decreases abruptly for lambda<1.15, and there is a minimum of elastic force for strong attraction interaction, then increases very slowly … painted barn
