Dear all

I found the EDIFF in INCAR is very important for elastic constants calculation. I want to know the EDIFF is the same or not for all elastic constants calculations? If yes, what is that? If not, how to find it? And it is possible to download by script? Because can only download the EDIFF in INCAR for GGA NSCF uniform.

from pymatgen.ext.matproj import MPRester

import pymatgen.core as mg

import re

import pprint

import pandas as pd

mpr = MPRester(“2bDBKRTo6dotrM66oRLZ”)

#mpid

a= mpr.get_doc(“mp-66”)

EDIFF = a[“input”][“incar”][“EDIFF”]

print(EDIFF)

Best wishes.
