A general purpose Lattice-Boltzmann code for fluid-dynamics simulations. It includes :

• fluid dynamics (with several volume forcing terms for Channel flow, Homogeneous Isotropic Turbulence, buoyancy)
• temperature dynamics (advection, diffusion , sink/source or reaction terms)
• phase change (enthalpy formulation for solid/liquid systems)
• scalar transport (same functionalities as temperature)
• lagrangian dynamics (tracers, heavy/light & active point-like particles; non-shperical Jeffery rotation, gyrotaxis)
• large eddy simulation (Smagorinsky, Shear Improved Samgorinsky with Kalman Filter)

Requirements:

• MPI
• HDF5
• CMake (optional)
