Weird fluctuations in Ising model

[QUOTE="mastrofoffi, post: 6000341, member: 573847"] Updating just in case anyone happens to come by and help me out. I created some animated plots for the 'weird' results and I found that they correspond to situations where two connected clusters(one for each spin) arise and reach some sort of equilibrium configuration where they are just translated ([U]always)[/U] in the [itex]-x[/itex] direction through the periodic boundary. Here a few pics of a 64x64 lattice taken at times 850,851,852,856: [ATTACH=full]225952[/ATTACH] [ATTACH=full]225953[/ATTACH] [ATTACH=full]225954[/ATTACH] [ATTACH=full]225955[/ATTACH] Basically it evolves for some time, then stabilizes on a configuration like this which is mantained for the rest of the simulation. This makes no sense at all to me: why would something like this happen? and how? I also tried rewriting the program all over, without looking at the original one, but I get the exact same thing. I guess this must be related to the periodic boundaries, so I'll try to implement free boundaries and see what happens. [/QUOTE]
