We present a suite of programs to determine the ground state of the time-independent Gross–Pitaevskii equation, used in the simulation of Bose–Einstein condensates. The calculation is based on the Optimal Damping Algorithm, ensuring a fast convergence to the true ground state. Versions are given for the one-, two-, and three-dimensional equation, using either a spectral method, well suited for harmonic trapping potentials, or a spatial grid
