pylbm is an all-in-one package for numerical simulations using Lattice Boltzmann solvers. This package gives all the tools to describe your lattice Boltzmann scheme in 1D, 2D and 3D problems. We choose the D'Humières formalism to describe the problem. You can have complex geometry with a set of simple shape like circle, sphere, ... pylbm performs the numerical scheme using Cython, NumPy or Loo.py from the scheme and the domain given by the user. Pythran and Numba wiil be available soon. pylbm has MPI support with mpi4py.
