Re: [Wien] Mixer error: NEC01 charge leakage too large

Your post is too large, but I'll answer here: Your struct and in1 file for TiC is ok. I'm not quite sure, why you have at the beginning the *broyd* present message ?? These files are produced by mixer. Did you run this before, with the same error or did it go through ? You had a save_lapw

Technically, you seem to do everything correct. When you split the 4 Fe into 2 sets, you break cubic symmetry. You also see it from the resulting Sg #74. Therefore there will be a relaxation ... (even without relaxation, you already broke cubic symmetry). Your approximation of an AFM

Hi Pablo, You repeat about the structure what I already told (maybe too short), if you check the intenational tables of crystallography you will find that there are two set-ups of the origin possible (0,0,0) or (1/8,1/8,1/8) in space group 227. Therfore, it is not unique if you give only the
