surface scattering

#1 Post by phtobias » Fri Mar 17, 2006 1:36 pm

Can VASP simulate the collision (sacttering) of a cold atom or molecular on the surface?

Thanks.

try to do it by a MD run (at sufficiently low T). Choose appropritae
initial velocities for the scattered atom / molecule (to be set in POSCAR)

Many thanks for the help. It works.

in case someone might be intereted in trying it out, below are the test input files.

Have fun!

I am new to vasp. Any coments are very welcomed.

P.S. please replace POSCAR with INCAR, or POTCAR, or KPOINTS (I will upate the OUTCAR/vasprun.xml on the website later).

Can anyone give me a hint for what is the 'predictor-corrector coordinates' in the CONTCAR. Thanks for the help.

what do you mean by 'predictor-corrector coordinates in the CONTCAR'.?

Sorry for not being specific. It is described in the link below, which I have no clue what it is,

http://cms.mpi.univie.ac.at/vasp/vasp/node63.html

It says:
-------------------------------------------
optionally predictor-corrector coordinates
given on file CONTCAR of MD-run
-------------------------------------------

Thanks for the continuous help.
