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. ---- <big>'''Features'''</big> * 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 <big>'''Upcoming'''</big> * Multiphase simulation component ---- <big>'''Current Developers'''</big> Misun Min [http://www.mcs.anl.gov/~mmin] CCNY Group: Taehun Lee [https://sites.google.com/site/leeccny/home], Kalu Uga, Saumil Patel <big> '''Related Projects''' </big> NekCEM [https://nekcem.mcs.anl.gov], Nek5000 [https://nek5000.mcs.anl.gov] ---- <big> '''Related Publications''' </big> * S.
