You can get the source from github with:
git clone https://github.com/CFD-GO/TCLB.git
cd TCLB
First you have to configure the compilation:
make configure
./configure
Then you can compile your selected model:
make d2q9
To run the solver, just execute the compiled solver with a selected configuration file (you can find some in the examples):
