Dear all, while performing some simulations in BH model (DWA code), I encountered problems with convergence in the vicinity of the critical point for small temperature T and a large linear dimension L. What is the root cause for the complexity of the simulation in such a case? I seem to get a large systematic error (which looks non-random as a a function of hamiltonian coupling constants). Is there any way to improve convergence?
While searching output hdf5 files for additional clues, and the DWA documentation, I have encountered the error_convergence in output files. Could I ask what exactly it is? Is it related to the "binning analysis" which has been discussed throughout the alps website?
Is there is a build-in method for convergence analysis? that would be very helpful.
