This is VOTCA, which provides the two following subpackages:

• VOTCA-CSG, a library which provides tools to develop coarse-grained potentials from atomistic simulation data
• VOTCA-XTP, a library providing the DFT+GW-BSE method to calculate electronically excited states in single molecules, in molecular materials with quantum-classical embedding, as well as electron, hole, and exciton dynamics in atomistic MD-trajectories.
