VASP is a density-functional theory code using pseudopotentials or the projector-augmented wave method and a plane wave basis set. This interface makes it possible to use VASP as a calculator in ASE, and also to use ASE as a post-processor for an already performed VASP calculation. truist bank smithfield va sign in
