Dear friends. I would appreciate if you could help me with using classic montecarlo simulation for fcc lattice on Heisenberg hamiltonian with s=1 and H=SIGMA Jij Si.Sj and Jij is just sum over nearest neibours.Would you mind telling me step by step that what should I do and exactly which codes I must use for this purpose?Its the first time I wanna use Alps and I dont know the steps of working with it. Many thanks for your helps. I would appreciate your immediate attention to this matter.
Are the couplings all antiferromagnetic? If so there is no way around the sign problem.

I've prepared simple example programs for classical Heisenberg models. Please download the latest ALPS (revision 6650 or later) and look at
