A new surface tracking algorithm for lattice gas automata Original Research Article

We introduce a simple interface-tracking algorithm for the lattice gas automata. In this model, the surface is explicitly tracked by tracers. Dynamics of the interface can be followed by applying special motion rules to the tracers. The motion of tracers consists of stretching and contracting, both of which can be composed by simple bit-operations. These rules enable the tracking of the complex topological changes of interfaces, such as coalescence and breakup of droplets, with the surface tracers.
