Title: Error in analyzing vasp output on VNL
Post by: TA on June 23, 2018, 00:07

I am trying to analyze vasp results (OUTCAR) using on VNL using OUTCAR file. I am; however, getting an error
saying "Unable to subtract physical quantity with None that has type :" I was wondering how can I fix this issue. I have made sure to include other outputs(PCDAT,OSZICAR,POTCAR...) in the folder containing OUTCAR.

Below are the details for the error:

"

Hi,

could you  be a bit more specific about the calculation, and mention if the calculation finished correctly?
