[CP2K-user] GEO_OPT on single atom catalysts graphene structure

Hi all,

I am trying to run geo_opt (with ASE python code) on a graphene structure 
with Copper in the middle and two nitrogens. I use maximum force of 0.01 as 
convergence criteria to start off. I included all the files below. My SCF 
does not converge and my energies seem to be going crazy... What is wrong 
with my input file?

These are the results:

  Step     Time          Energy         fmax
*Force-consistent energies used in optimization.
LBFGS:    0 16:50:20     9139.239727*    1687.8341
LBFGS:    1 16:52:29    13502.225247*    1231.9027
LBFGS:    2 16:54:31    11300.743617*     987.9389
LBFGS:    3 16:56:52    20088.494364*    1986.4853


Thanks,

Hasan.
