I am kind of new in CP2K code and I need some recommendations to improve my calculations. I am trying to use the Quickstep method (GPW) implemented in cp2k to optimize a system formed by an organic molecule deposited on top of a 2D magnetic semiconductor. I tried with this setup (see input and output attatched) and the result slowly converges (1.0E-5 SCF accuracy) in 700 steps and in some cycles of optimization it does not converges in this amount of cycles. I read in the Prof. Jürg Hutter lessons that for a semiconductor system the OT method is efficient, but I do not know if I am configurating it properly.<div><br></div><div>Which parameters could I add/remove? Should I move to GAPW method? Thanks in advanced.</div></blockquote></div>
