Module lbm_api 

Lattice Boltzmann Method (LBM) simulation API for Python interop.

Provides PyLbmSimulation: a 2-D D2Q9 LBM solver with BGK collision, configurable boundaries (no-slip walls, periodic, inlet/outlet), and full velocity and density field extraction.

Structs

LbmStats

Per-step statistics for a 2-D LBM simulation.

MrtRelaxation

MRT relaxation rates for D2Q9 (9 rates, one per moment).

PyLbm3dConfig

Configuration for a 3-D D3Q19 LBM simulation.

PyLbm3dSimulation

A 3-D D3Q19 Lattice-Boltzmann simulation.

PyLbmConfig

Configuration for the LBM simulation.

PyLbmSimulation

A 2-D D2Q9 Lattice-Boltzmann fluid simulation.

Enums

LbmBoundary

Boundary condition type for an LBM cell.

Functions

apply_moving_wall_3d

Apply a moving-wall (Zou-He) velocity boundary to a row of cells.

zou_he_pressure_outlet

Zou-He outlet boundary condition: prescribe zero-gradient at x = width-1.

zou_he_velocity_inlet

Zou-He inlet boundary condition: prescribe velocity at x=0.
