[CP2K-user] Bulk Copper CELL_OPT oscillating

[mdsimula... at gmail.com]

Hello,

I am attempting to optimize a copper cell (CP2K v. 6.1) using LBFGS.  It'll 
get to the 7th optimization step and then it seems like it's just 
oscillating.  I've attached my input and the output files.  Any suggestions?

Thanks,
Stacey
