For optimum performance the collision and streaming kernels should be specialized for the chosen layout. \n\n\n## See also\n\nSome of these libraries may also be used in the future:\n\n- [Medusa](https://e6.ijs.si/medusa/wiki/index.php/Medusa)\n- [Eigen](http://eigen.tuxfamily.org/index.php?title=Main_Page)\n- [Boost](https://www.boost.org/)\n- [nanoflann](https://github.com/jlblancoc/nanoflann)\n- [psblas3](https://github.com/sfilippone/psblas3)\n- [librsb](http://librsb.sourceforge.net/)\n\n## Other codes\n\nFor large-scale simulations consider using one of the following freely availables codes\n* [waLBerla](https://walberla.net/)\n* [Palabos](https://palabos.unige.ch/)\n* [TCLB](https://github.com/CFD-GO/TCLB)\n* [Musubi](https://geb.inf.tu-dresden.de/doxy/musubi/index.html)\n* [OpenLB](https://www.openlb.net/)\n* [VirtualFluids](https://git.rz.tu-bs.de/irmb/virtualfluids)\n\nFor industrial purpose simulations the following solvers can also be used\n* Dassault Systèmes Simulia [PowerFLOW](https://www.3ds.com/products-services/simulia/products/powerflow/) and [XFlow](https://www.3ds.com/products-services/simulia/products/xflow/) (formerly from Exa Corporation)\n* Altair [ultraFluidX](https://www.altair.com/altair-cfd-capabilities/#lbm) (formerly from FluiDyna GmbH)\n* [ProLB](http://www.prolb-cfd.com/)\n\nA bunch of other (mostly research oriented) codes are described in [the list](https://github.com/sthavishtha/list-lattice-Boltzmann-codes) by Sthavishtha Bhopalam Rajakumar ([@sthavishtha](https://github.com/sthavishtha)).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fivan-pi%2Fperiodic-lbm","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fivan-pi%2Fperiodic-lbm","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fivan-pi%2Fperiodic-lbm/lists"}
