That tutorial doesn't really give a good procedure for production work
simulations. Use a rhombic dodecahedron instead, with a distance to
the wall (-d) of at least 1 nm. Maybe it's better to try the tutorial
I put up on http://nmr.chem.uu.nl/~tsjerk/course/md-tutorial/ It's not
as good on the graphics, but the procedure is closer to what you need
for proper simulations.
