VASP Source Code

What is VASP Source Code?

The VASP (Vienna Ab initio Simulation Package) source code is a highly optimized and proprietary software used for performing quantum mechanical molecular dynamics and electronic structure calculations using density functional theory (DFT), many-body perturbation theory (MBPT), and hybrid functional methods. Written primarily in Fortran, the code is designed for high-performance computing environments and is capable of simulating systems with periodic boundary conditions. The source code implements plane-wave basis sets, pseudopotentials, and projector augmented-wave (PAW) methods to achieve accurate results for condensed matter and materials science research. Access to the source code requires a commercial license from the VASP Software GmbH.
