Unzipping this file should form a folder sss (for "Solid State Simulations", Silsbee's project for Physics 454). You can also download the entire distribution, except that the presets and exercises for "ising" will be different. Source code is also available.)
Go into the new sss folder, go into bin, and execute galileo (or pythag, or schrdgr ...). You can't move the executables without moving the whole sss directory folder. If you have any problems, let me know.
