you first have to be sure that you can converge the wavefunction.
Only if that works fine you should start MD.
Also try to avoid diagonalization, use OT if possible.
Finally, if all works fine and you can try to get stable MD and
optimize the localization.

Subject: [CP2K:9868] how to boost the MD simulation?

Dear all,

in order to determine the infrared (IR) and raman spectrum of interfacial water at LiNbO3, MD simulation was run using CP2K (module version 3.0, because 5.1 does not run due to possible bug with intel) with calculation of wannier centers (wannierout.xyz). I set the calculation for 4 days and after this time I got output files which contain results of only 3 steps. Why the calculation took so long for only 3 steps? Is there any mistake in the input file and how can I boost the MD simulation with wannier center calculation?

Kind regards,
