Speed up stencil computations on numpy arrays.

HyTeG (Hybrid Tetrahedral Grids) is a C++ framework for large scale high performance finite element simulations based on (but not limited to) geometric multigrid.

waLBerla (widely applicable Lattice Boltzmann from Erlangen) is a massively parallel framework for multi physics applications.

Generate pystencils kernels for waLBerla

Run fluid simulations based on the lattice Boltzmann method.
