Re: NEB image has lower energy than the fixed initial point

Thank you very much for your reply Dr. Graeme! Can I clarify something, what do you exactly mean by minimizing that image? Does it mean that I need to relax the image? I checked my INCAR file and the only difference that I made was to lower the convergence criterion for the NEB run (I used EDIFFG = ...

NEB image has lower energy than the fixed initial point

I am doing NEB calculation on water splitting on certain surfaces, and after NEB convergence and looking at the results, I found out that the 1st image has a lower energy than the 0th image which is the fixed initial point. Is this reasonable or does this make sense, considering that the fixed point...

Calculation of Charge Transfer and results

Greetings! I am new to bader charge analysis, and I would like to do some test calculations on surface-adsorbate interaction. I know that in order to calculate the charge transfer between adsorbate and surface, the usual method is to calculate first the bader charge on the surface+adsorbate, surface...
