CudneLB is a MPI+CUDA or MPI+CPU high-performance CFD simulation code, based on Lattice Boltzmann Method.

It provides a clear interface for calculation of complex physics, and the implementation of new models.

Just clone the repo (or download the zip file):

git clone https://github.com/CFD-GO/TCLB.git
cd TCLB

If you want a more recent (but less stable) version, you could try the development branch:

git clone -b develop https://github.com/CFD-GO/TCLB.git
cd TCLB

You'll need:

• R
• packages for R: optparse, numbers, rtemplate, gvector, polyAlgebra
• nVidia CUDA (if you want to use GPU)
• python, numpy (if you want to use the integrated python interpreter)
• python, sympy and R package: rPython (if you want to develop a model using python instead of R)
• MPI (e.g. OpenMPI)

You can install many of these with the tools/install.sh script (note it requires sudo):

sudo tools/install.sh cuda 6.5-14 # only if your GPU supports cuda
sudo tools/install.sh r
sudo tools/install.sh openmpi
     tools/install.sh rdep
sudo tools/install.sh python-dev
     tools/install.sh rpython
sudo tools/install.sh module # only on CentOS

The install.sh script is designed to work on Ubuntu (e.g. on the Travis-CI VMs). The install.sh script should work on CentOS. You can install the sudo parts by yourself, and use script to install R packages: rdep and rpython.

This should work:

module load mpi/openmpi-x86_64 # only on CentOS
make configure
./configure --enable-double --enable-graphics --with-cuda-arch=sm_20 
# only CPU ./configure --enable-double --disable-cuda
make d2q9

This should also work:

CLB/d2q9/main example/flow/2d/karman.xml

The documentation (including tutorials) is published at docs.tclb.io. You can contribute at CFD-GO/TCLB_docs.

For the develop version, most recent documentation can be found at develop.docs.tclb.io.
