The flow through a simplified honeycomb model of eight channels was simulated with the lattice gas automata method. Comparison of automata results shows good agreement with those of the finite difference method, confirming the suitability of the lattice gas automata method. The program was designed to locate any stagnant flow regions that formed, and to automatically convert these regions into obstacles, using this obstacle process. Then the ratio between the maximum and minimum flow rates in the channels decreased by 27%. Also, parallel processing was experimented with in conjunction with the lattice gas automata method, and its adaptability was evaluated. The rate of increase in calculation speed was found to be largely proportional to the number of processors, and that parallel processing was useful and could calculate rapidly.
