Lattice Gas
Here is some code, lgcode9.tar.gz , to
implement the FHP-III lattice gas in two dimensions. It is a
modification of the lattice gas code by
Dan Rothman and Stéphane
Zaleski. Check their site for updates as well. Some or all of
these modifications will be included in their code eventually. The
modifications include a couple of bug fixes that can give incorrect
results for some parameters. The code given here is only one
subdirectory, correpsonding to one model, of their code. A brief,
(and currently incomplete) description is in the README . A number of added features, such as tracer
particles and different forcing rules, are not well documented, but
I hope to add this in the near future.
