摘要：
我们提出了一套程序来确定用于玻色-爱因斯坦凝聚体模拟的与时间无关的Gross-Pitaevskii方程的基态。计算基于最优阻尼算法，确保快速收敛到真实的基态。版本给出的一，二，三维方程，使用频谱方法，非常适合谐波捕获的潜力，或空间网格。
英文摘要：
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.
