The Problem with running vtotav.f script

#1 Post by suleechem » Thu Nov 23, 2017 7:09 am

Hi VASP users,

I am trying to calculate the work function of single sheet like graphene with molecules on the surface. I am using the vtotav script to average the potential.

I have a error when using vtotav:

Which direction to keep? (1-3 --- 1=X,2=Y,3=Z)
3
34
positions read
Error opening or reading file LOCPOT.
item : 35
The LOPCOTfile contain 41 atoms, not 81 but error note 34 atoms. I do not know the meaning of this error massage.

The important information of the LOCPOT file is shown below,

Could you help me solve this problem?

Or Could anyone provide a script for people who investigate a single sheet system like graphene instead of a slab model like me?

Best regards
