Lucas,
True, SIESTA always checks if it is an atom, molecule or solid, but it
**does** use periodic boundary conditions, always. From the siesta
manual:
LatticeConstant (...) Default value: Minimum size to include the system
(assumed to be a molecule) without intercell interactions, plus 10%.
So
SIESTA always uses periodic boundary conditions. There is a default box size,
I think it's cubic and its default side must be specified in the manual. You
had better specify it explicitly, in whatever shape and size you feel is
appropriate.
No, if you just put the position of the atoms in wicheve
Hi,
has anybody a tested basis set for N in organic compounds with semicore ?
Thanks.

fellows,
I have started to use Siesta recently. Sorry, if my
questions sound naive.
1. By computing a molecule I removed from the input
file the variables related to the perdic box, however,
at the end "Cell volume" is printed. What it is? If
there is a deafult box size it may be too small.
