This repository contains a (largely unmodified) fork of the LB code Palabos as distributed by FlowKit Ltd. via palabos.org.
Maintainer: Philippe Seil (philippe.seil@jku.at), Johannes Kepler University Linz, Austria
The existence of three branches in this repository is guaranteed:
- master: contains both Palabos and additional utilities developed by PFM/JKU. Palabos is usually unmodified except for minor bugfixes in case they arise and a few tiny issues (see next section). Utilities are found in externalLibraries/plb/utils.
- develop: Development version. May contain newer features, but may break.
- plb-vanilla: contains the unmodified content of the latest version of Palabos.
Other branches present are usually temporary feature branches and should by no means used in any productive environement.
In Palabos, the relaxation rates for MRT dynamics are preset to values from literature. However, most people nowadays use either the TRT relaxation by Ginzburg et al. (2008) or the relaxation rates of Pan et al. (2006). Those two settings can now be used by defining
#define MRT_USE_TRT_RELAXATION
or
#define MRT_USE_PAN_RELAXATION
before the
#include "palabos3D.h
#include "palabos3D.hh"
commands in your case file. A "magic number" of 3/16 is hardcoded (gives best bounceback).
