I see. If the slab is located in the middle of the cell (i.e. at 0.5 in crystal units) then the dipole layer at 0.0 is OK! In this case here is the suggestion: Your 1 V/Angs is rather strong field. First perform SCF with lower field or no field (what Paolo suggested) and then use that as an input guess. Regards, Tone -- Anton Kokalj J.
