 | L2 | `modelcraft-lbm` | Lattice Boltzmann flow solver on the CPU: D3Q19 two-relaxation-time scheme, bounce-back and slip walls, Zou–He inlets and outlets, obstacles voxelised from the face-tagged surface with exact predicates, momentum-exchange forces per face. Uses `mesh` for the predicates and the boundary surface. | started |

Bytes in, bytes out; the file system only in `fs` and `recovery`. Result files later. | started |
