NEB apparently hangs
Posted: Thu Feb 23, 2023 11:07 am
I have installed VTST tools 6.3 in Vasp 6.3.2. While there are no test suites to run, I did try the standard Vasp NEB tutorial and it worked fine. In the problem I wish to solve, I have two phases with different lattice vectors requiring the use of LNEBCELL. I used nebmake.pl to make five image POSCAR files along with the beginning and ending structures from 00 to 06. The program seems to run fine, but hangs after a single SCF convergence. The console outputs indicates no apparent errors, but apparently hangs after the first iteration. A similar OSZICAR can be found in each of the image directories. I have attached the (smaller) files in each directory for reference. I would be grateful fi a hint could be offered as to what I am doing incorrectly.
