vacancy migration NEB

Post by vasp0405 »

For the NEB calculations of vacancy migration, the cell shape and volume for all images including initial and final ones should be fixed or not? Thanks.

That is really a question about the science If you are trying to get an activation energy for a vacancy migration in a bulk material, I would recommend keeping both the cell size and shape fixed.
