POTCAR

Could be downloadable from: /usr/local/vasp/ Depending on which potential you would like to use, go to:

• PAW (Projected augmented wave),
• PAW-GGA (Projected augmented wave-generalized gradient approximation),
• PS (Pseudopotential) etc.

To access these files you need to be a member of vasp group. There are four sub-folders: pot, pot_GGA, potpaw, and potpaw_GGA at /usr/local/vasp/.
