Welcome to NekCEM

NekCEM https://svn.mcs.anl.gov/repos/NEKCEM is a high-fidelity, open-source electromagnetics solver based on spectral element and spectral element discontinuous Galerkin methods, written in Fortran and C. The code is actively developed at Mathematics and Computer Science Division of Argonne National Laboratory.
