1. Data analysis Once equilibrium seems to have been reached and the simulation has run for an adequate number of cycles, the command "./make-Ehist n" takes the last n outputs at each temperature and generates energy histograms for use in multiple histogram analysis. By default there are only 100 bins, but this can be easily changed. Similarly, "./cvm-entropy.py n" takes the last n outputs at each T and calculates the entropy according to a sequence of CVM approximations: point, NN, NN+NNN, triangle, and tetrahedron. 2. Conventions In the tetrahedra energies file, MC structure configuration files, and much of our simulation code, we denote each of the N species of an alloy with 1 through N. So in our example: 1 - Mo, 2 - Nb, 3 - Ta, 4 - W. 3. Systems other than MoNbTaW The programs in this suite are specifically suited for studying equiatomic MoNbTaW and as such many of the codes are not immediately usable for other alloys. However, modifying them to work with different alloy systems or different compositions requires minimal modification.
