Computer modelling techniques thresholds

Dynamic simulation approaches to model kinetic percolation are difficult to implement because of the inherent complexity of the problem, which requires intensive computation. As with any kinetic modd, the duration of the simulation must be commensruate with the critical timescales of the experiments. An early study to investigate the effeas of interactions on the percolation threshold was conducted by Bug et al. Here, a continuum Monte Carlo algorithm was used to modd a small system of 500 spherical particles undergoing Brownian motion. More recently, advanced simulation approaches such as Dissipative Particle Dynamics (DPD) have been applied to study kinetic percolation in composite sys-tems. " DPD is an off-lattice simulation technique similar to molecular dynamics, but applied to the supramolecular scale. Here, the larger-scale dynamics of a system are studied by monitoring the motion of particle clusters in response to pairwise, dissipative, and random forces. ...
