pyLBM is an all-in-one package for numerical simulations using Lattice Boltzmann solvers.
pyLBM is licensed under the BSD license, enabling reuse with few restrictions.
pyLBM can be a simple way to make numerical simulations by using the Lattice Boltzmann method.
To install pyLBM, you have several ways. You can install the last version on Pypi
pip install pyLBM
You can also clone the project
git clone https://github.com/pylbm/pylbm
and then use the commands
pip install -r requirements.txt
python setup.py install
or
pip install -r requirements.txt
python setup.py install --user
Once the package is installed you just have to understand how build a dictionary that will be understood by pyLBM to perform the simulation. The dictionary should contain all the needed informations as
To understand how to use pyLBM, you have a lot of Python notebooks in the tutorial.
The most important classes
Geometry (dico) |
Create a geometry that defines the fluid part and the solid part. |
Domain ([dico, geometry, stencil, ...]) |
Create a domain that defines the fluid part and the solid part and computes the distances between these two states. |
Scheme (dico[, stencil]) |
Create the class with all the needed informations for each elementary scheme. |
Simulation (dico[, domain, scheme, sorder, dtype]) |
create a class simulation |
