Welcome to NekLBM
NekLBM https://svn.mcs.anl.gov/repos/NEKLBM is a high-order lattice Boltzmann fluid solver based on spectral element discontinuous Galerkin methods. It is an open-source code written in Fortran and C. The code is actively developed at Mathematics and Computer Science Division of Argonne National Laboratory.
