Lattice Gas Automaton - Advantages and Disadvantages

Advantages and Disadvantages

The main assets held by the lattice gas model are that the boolean states mean there will be exact computing without any round-off error due to floating-point precision, and that the cellular automata system makes it possible to run LGCA simulations with parallel computing.

Disadvantages of the lattice gas include the lack of Galilean invariance, and statistical noise. Another problem is the difficulty in expanding the model to handle three dimensional problems, requiring the use of more dimensions to maintain a sufficiently symmetric grid to tackle such issues.
