Hi everybody,
I've recently started using the Dimer method and it worked perfectly for most systems, but in one case at one point significant rotation of the dimer stops although the torque is still higher than 1. I'm using ALGO = Normal and EDIFF = 1E-08 for high accuracy, increased DRotMax to 20 and tried DdR = 0.005 and 0.01, but in any case it happens. Below is my current DIMCAR.
Any help would be appreciated!
Thanks,
Josua

Re: Dimer method, difficult system
If you post the input files and the OUTCAR (e.g. as a .tar.gz file) we'll take a look and see if we can get to the bottom of the problem.

Alright, here it is. Thank you so much!

Re: Dimer method, difficult system
The problem disappeared when I used a slightly different starting geometry. So the problem isn't affecting me anymore although I would be curious what exactly it was
