Pseudopotential generators (standalone)
-- Somewhat out of date. Has excellent hands on tutorial.
-- Troullier Martins pseudopotentials and MRPP method for
treating interior shells.
DFT codes I have used
-- Spanish Initiative for . . .
Combines use of pseudopotentials and finite-range atomic orbitals
for maximum speed.
-- open-source plane-wave pseudopotential code. Has excellent tutorial
of general value in how to do DFT calculations.
-- open-source FLAPW code.
-- almost exhaustive library of exchange-correlation functionals,
interfaces with APE, Abinit, Elk.
-- official source code.
