RASPA3

This software is a general purpose classical simulation package.

It has been developed at the University of Amsterdam (Amsterdam, The Netherlands) during 2022/2026 in active collaboration with Eindhoven University of Technology (Eindhoven, Netherlands), Delft University of Technology (Delft, The Netherlands), and Northwestern University (Evanston, USA).
