Computational fluid dynamics (CFD) simulations are essential tools in various scientific and engineering disciplines. Nek5000 is a CFD Fortran code based on spectral element methods with a proven track record in numerous applications. In this article, we present Snek5000, a Python package designed to streamline the management and visualization of fluid dynamics simulations based on Nek5000. The package builds upon the functionality of Nek5000 by providing a user-friendly interface for launching and restarting simulations, loading simulation data, and generating figures and movies. This paper introduces Snek5000, discusses its design principles, and highlights its impact on the scientific community.
