Dear user,
I'm trying to calculate single point energy of cluster system which has 100 atoms.
This system need to do pbc environment but I'd like to calculate one unitcell of it without pbc and thus the structure is very far from optimized structure.
When the calculation begin, the odd part is, only input.db file is came out and no other files occurred.
Also, output file shows no progress after "Time prior to 1st pass: " sentence.
Does anyone know how to handle this problem?
here is my input file
title
echo
memory 1900 mb
geometry noautoz units angstroms
symmetry group c1
symbol x y z coordinate
end
basis spherical
Si library 6311++G(2d,2p)
C library 6311++G(2d,2p)
O library 6311++G(2d,2p)
F library 6311++G(2d,2p)
H library 6311++G(2d,2p)
end

Thank you in advance.
