[DFTB-Plus-User] Calculation is not finished

[u3129004 at edu.gifu-u.ac.jp]

Dear DFTB+ user,

Now I am calculating the transmission for armchair graphene nanoribbon 
terminated by hydrogen. I think this system is not so large, but it 
takes very long time. It is repeating "COMPUTING DENSITY MATRIX" and "
SOLVING POISSON EQUATION". I attached my input file.

It would be very helpful if you could give me any advice.

Thank you very much in advance,
Kazuma
