3.2 Motion 3 Overview of the SCL Implementation 3 Overview of the SCL Implementation 3.1 Space and Time SCL implements the reaction scheme in a discrete, 2D, space with toroidal topology.
Time is also discrete.
The space is organised as a square lattice. Each cell in the space is occupied by a particle object. Bonds are also represented by objects of another separate class. Lists are maintained of all particles of each class, and of all bonds. The basic execution cycle of the model, for one timestep, is that each such list is traversed in turn, and each particle or bond is sent a step message.
