**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
