Hi, I'm new to  CP2K and I want to use  DFT+U i wanted to optimise a MOF 
structure with 6 Fe atoms in it, and I'm wondering what multiplicity I 
should assign to the input file.
Should I leave it 0 or assign another multiplicity with a magnetisation 4.0 
for Fe  / I'm working on the adsorption studies - i need a DOS and PDOS to 
check for orbital hybrdi . 
DFT+PBE does not work in my case.
Thanks in advance.
