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.


Features

  • Lattice Boltzmann approach for collision step
  • Spectral element discontinuous Galerkin discretization for advection step
  • Advection-diffusion equation solver for heat transfer
  • Hexahedral body conforming meshes
  • The 4th-order Runge-Kutta timestepping
  • The high-order exponential time integration
  • Flows past a cylinder and cylinders in tandum
  • Flows past a hemisphere
  • Turbulent flows in a channel
  • Natural convection flows in a square and an annulus
  • high parallel efficiency scaling over 100,000 cores
  • parallel IO scaling over 65,000 cores

Upcoming

  • Multiphase simulation component
