Hello everyone, when cp2k does GEO_OPT, the displacement in BFGS, why is 
the input and output different? In this case, how should I control the 
movement step of the atom?
grep "RADIUS" cp2k.inp
          TRUST_RADIUS     0.2
 grep " Trust radius:" cp2k.out
          BFGS| Trust radius:      0.378


Any feedback would be much appreciated! Thanks for taking a look at my 
issues. 

With much appreciation, 

lingd
