Taichi Lattice Boltzmann (tilb) is an implementation of the lattice-Boltzmann method in Taichi. The code is loosely based on LBM_Taichi project but with significantly redesigned code to improve performance and handle a wider set of boundary conditions. If you use this code, please cite
Tomczak, T. Data-Oriented Language Implementation of the Lattice–Boltzmann Method for Dense and Sparse Geometries. Appl. Sci. 2021, 11, 9495. https://doi.org/10.3390/app11209495
tilb is designed as the main library (tilb.py file) and separate script used for setting and running a simulation. Four example simulation are provided:
- lid-driven cavity (file
cavity.py), - channel flow (file
channel.py), - flow past cylinder (file
cylinder.py) - flow through sparse geometry with given porosity (file
sparse.py)
The simulation can be run by simply running given script, for example:
ti cavity.py
launches lid-driven cavity simulation.
Simulations script contain commented sets of different settings, for details please consult the source code (I hope it is self-explaining). Each simulation has the main function simulate(), which builds the case and launches computational engine. At the end of simulation, file out.vts is generated, which can be further processed with ParaView.
