[CP2K-user] [CP2K:16498] Re: error in check_diag:check of matrix diagonalization failed

Hi,

The input you attached does not work because it has incompatible poisson 
and periodicity settings. I assume you ment to use PERIODIC XYZ in the 
&POISSON section.
I can run this input without error. I changed ALPHA in &MIXING  to 0.1 and 
the GEO_OPT converged (but with quite a large reconfiguration of the 
structure).

Cheers,
Fabian
