# NekRS [NekRS](https://github.com/Nek5000/nekRS) is a fast and scalable open-source CFD solver for HPC applications, developed at Argonne National Laboratory. It solves the incompressible and low Mach-number Navier-Stokes equations using high-order spectral element methods on CUDA, HIP, DPC++, and CPU backends. ## Examples ```{toctree} :maxdepth: 1 Poisson Turbulent Channel ```
