<div>Hi all, I am pretty new to DFT and trying to run some single atom (C) DFT to use as a subtraction when fine tuning a machine learned force field for MD. As such it needs to be run at the same level of theory as my full system calculations. <br /></div><div><br /></div><div>I just need single point energies. <br /></div><div><br /></div><div>At the moment it is not converging, I have attached my input and output files, i am using the omega97X-D functional. <br /></div><div><br /></div><div>Some thing I have tried include: <br /></div><div><ul><li>Changing the box from periodic to non periodic</li><li>Reducing mixing</li><li>Increasing & decreasing the size of the box <br /></li><li>Changing multiplicity <br /></li><li>Reducing cutoff <br /></li></ul><div>The energy change per step seems to reduce over steps but does not converge. <br /></div><div><br /></div><div>I am using the DZVP-MOLOPT basis set and GTH-PBE-q4 potential as suggested in here: https://www.cp2k.org/exercises:2018_uzh_cmest:faq <br /></div><div>potentially that is the issue? <br /></div><div><br /></div><div>Would appreciate any help you can provide <br /></div><div><br /></div><div>Thanks</div></div>
