The HFB3 code is a solver for the Hartree–Fock–Bogoliubov equations applied to atomic nuclei. The single-particle wave functions are discretized on a basis of solutions of either a single-center harmonic oscillator or a two-center one. The implemented nuclear interactions are of the Gogny type.

The first version, HFB3-1.0, is open source and available on this Git repository. A companion publication can be found in Eur. Phys. J. A.: N. Dubray et al., Eur. Phys. J. A. 61 (2025)
