NEK5000
From CFD-Wiki
NEK5000 is an open source (licensed under the GNU General Public Licence) spectral element CFD code developed at the Mathematics and Computer Science Division of Argonne National Laboratory. NEK5000 is highly scalable and was recognized with the 1999 Gordon Bell prize for algorithmic quality and for sustained performance on 4096 processors of ASCI-Red. NEK5000 features some of the first practical spectral element multigrid solvers, which are coupled to a highly scalable parallel coarse grid solver.
