CA-muSE: download
HOW-TO
Gunzip and untar the downloaded file. Go into CA-muSE/input. You can change the system size, number of time steps, and total amount of time in the corresponding files. It might be a good idea not to change the constants - lambda and L.
In CA-muSE, the "make" command will produce the required CA-muSE.out executable.
