I am planning to simulate a turbulent flow with a relatively low Reynolds number using LBM, can anyone recommend a suitable open source code? OpenLB or Palabos or others?
Thanks!
Hello
Professor Jos Derksen, has developed a very efficient FORTRAN LBM code.
We used it and it works.
Here is his last paper :

Dear Mister Xu,
There is this nice code from Erlangen (Germany) called waLBerla.
You can find the details here: http://walberla.net/

Among the two i think Palabos is more stable one. There is a book authored by Prof A Mohammad. Few basic codes are given there. I recommend you start with that.
OpenLB has accurate turbulence models implemented, some in joint work with PhD students of Adams (TUM). The results has been published and validation examples are provided.
Next February there will be a Spring School on LBM and OpenLB (cf. www.openlb.net/spring-school-2019). There, you will get help getting started with the code.
It depends on the problem that you have in hand. Both OpenLB and Palabos are excellent codes. If you have a complex geometry that requires large computational resources, then following codes might also be worth looking at:
- Musubi: https://bitbucket.org/apesteam/musubi
- WalBerla: http://www.walberla.net
http://exolete.com/lbm/ has also nice 2D/3D codes for learning purposes.
As previously stated, depends on your targets. For example, when I was looking for multicomponent model I found it in OpenLB.
Also, the good thing about OpenLB is that it outputs VTK format which is possible to visualize in ParaView. I am not sure if you can do it with Palabos.
