[Wien] How I can determine the equilibrium interlayer distance between bilayer graphene?

[Jaafar Jalilian]

We can investigate equilibrium interlayer distance (ID) by two method:
1- Using force relaxation at software (miniposition)
2- calculating energy versus interlayer distance, and choosing minimum point
But these methods give different values, for example ID(1)=3.4, ID(2)=4.5
angstrom.
In your opinion, which method provides the correct value?
