Hi all,<div><br /></div><div>I hope you are all doing well. I am following up on a prior message I sent regarding a CP2K simulation setup used to model the collisional surface interactions between an incident EMIBF4 neutral traveling with a known velocity at a gold surface. I have since reduced the size of the gold surface from 1024 atoms to 128 atoms. Although, it seems that the SCF wavefunction optimization is struggling to converge. I was wondering if there were any guidelines or suggested methodologies for operating with metallic systems and how to better ensure convergence for the system I've described. I've attached the input script (surface.inp). Please let me know if you have any additional questions and I look forward to hearing from you!</div><div><br /></div><div>All my best,</div><div>Nick</div>
