Hi all..............
I want to work on graphene sheet using VASP, like calculating electronic properties. But somebody told me that it is computationally expensive.is it really so? what should i do?

The computational demands depend on what you want to do with the graphene sheet (defects, adsorption, use of hybrid functionals, etc..), and are always relative to what kind of resources you have access to. Just a clean perfect graphene sheet with LDA/GGA is not computationally expensive.

Cheers,
