This you should be able to answer yourself, 1) What does k-points implicitly mean in calculations? 2) Is that meaning compatible with your simulation? 3) In your simulation, what would be the difference between a k-point simulation and a non k-point simulation? 2015-08-28 14:14 GMT+02:00 leoqmc .

Transiesta does not per default update the density in the electrode regions. So unless you have a really long extended electrode region "on-top" of your bulk electrodes, you should not see any difference. "Bias" can be anything... "TS.BiasContour.NumPoints>30" is really an arbitrary number unless
