stress unit convertion from kB to GPa? potcar for He?

#1 Post by lqzhang » Thu Feb 14, 2008 3:51 am

Dear administer:

When searching in vasp source code, I could not find out how its unit for stress kB is defined and how to convert it into GPa, could anyone tell me where I could find out answer? Thanks a lot.

Another question, I need to insert noble gas He into silica system. But I found no POTCAR file for He in vasp document. The directory under He is empty. So what should I do with that? thanks a lot.

1. As far as I know you have 1 kB = 10^3 bar = 10^8 Pa = 0.1 GPa

2. Have the vasp-responsible in your group checked the ftp-server? There is at least He - PAW potentials.

Best regards
