Hi Francesco,
here is my input file. I have 4.38A lattice constant, so 6.05A is
definitely some wrong value (it is probably the Cd-Cd distance but not
the lattice constant).
Alex.


Hi Alex, tested it, definitely needed the combination of 2 KB proj and pushing mesh up to 300 Ry as you suggested. Not needing such fine k-point sampling, ok with 10 A (ok as it' s an insulator). Also works with the siesta provided (non-relativistic) TM2 psfs, got similar lattice constant and gap,
maybe needing a slightly smaller mesh with 200 Ry.

Thanks a lot !!!

Francesco
