Part 2: Lattice structure
The original ZGB model was simulated on a rectangular lattice (coordination number 4). Zacros has this structure implemented as a default lattice, along with a hexagonal and a triangular lattice (coordination numbers 6 and 3). To use one of the default lattices, one has to start the lattice_input.dat with the keywords:
lattice default_choice
The rectangular lattice is then invoked by the keyword rectangular_periodic, which is followed by one real, specifying the lattice constant, and two integers, specifying the size of the lattice. In the following, we construct a 50×50 lattice with lattice constant equal to 1:
rectangular_periodic 1.0 50 50
Thus, the full contents of the lattice_input.dat file are as follows:
lattice default_choice
rectangular_periodic 1.0 50 50
