Re: Ion Diffusion through 2D material convergence issues

Unfortunately, I am unable to share the exact calculation from the system that I was talking about in the original post, however, I can share a similar calculation. Everything is behaving the same, except some images are still converging to below 1 eV/A. Hopefully this will help with figuring out ...

Ion Diffusion through 2D material convergence issues

Hi all,

I am using this tool to study single ion diffusion through graphene. I am able to get the forces below 1 eV/A pretty easily, but after that, each image's forces will oscillate. I have tried using IOPT=3 and 7, along with varying the TIMESTEP tag, yet the system's forces are still now ...
