Fen,

Supposing your geometry is correct, I suggest you set DM.MixingWeight
to a low value, say 0.05 or lower ; NumberPulay to 10 or higher. You
can also set a rather high electronic temperature, say, 100 meV for an
initial relaxation, then starting from the last positions, lower the
electronic temperature and so on until it is low enough.

Also, note that the default value for PAO.EnergyShift will be used,
instead of the value you intended. There is a typo in your fdf file.

Good luck,

Marcos

PS: you can always generate an xyz of the system, especially if your
coordinates are already in Angstroms; it suffices to follow the xyz
file format or, if you are feeling too lazy to do things by hand, set
parameters like cutoff to 10 ry, set number of scf steps and cg steps
to zero, gamma point sampling only, and the basis set to SZ. You'll
have the xyz file in 5 seconds or less...
