SHTns是高性能的球谐变换库。它的目的是在球面几何形状的数值模拟（流体流动，MHD等）。这是非常快的，仔细的量化和运行调整的感谢。它通过OpenMP的支持多线程转换。它具有标量和矢量变换，合成和分析，灵活截断，正常化。包含一个Python接口。
SHTns is high-performance Spherical Harmonic Transform library. It is aimed at numerical simulation (fluid flows, mhd, etc.) in spherical geometries. It is very fast, thanks to careful vectorization and runtime tuning. It supports multi-threaded transforms via OpenMP. It features scalar and vector transforms, synthesis and analysis, flexible truncation, and normalization. A Python interface is included.
