Re: NEB computation for CH3O + H reaction
[quote="kambiz"]Hi,
Sorry, but just a question,
So after using IOPT=7, all forces are less than 0.1 and then after using IOPT = 1, the job is not converging??

Yes. I have done some NEB calculations, my experience is that It is hard to converge using IOPT=1 and EDIFFG=-0.03 after ...

NEB computation for CH3O + H reaction
Dear everyone,
I want to compute the reaction barrier of reaction CH3O + H --> CH3OH on Cu(111) surface in order to reproduce others work. I adopt 6 images and firstly converge with the setup:
IOPT=7, timestep=0.01, EDIFFG = -0.1, ENCUT = 300, PREC = normal (decrease computation cost)
after ...
