OpenLB – Open Source Lattice Boltzmann Code

Unofficial mirror

The OpenLB project provides a C++ package for the implementation of lattice Boltzmann methods that is general enough to address a vast range of tansport problems, e.g. in computational fluid dynamics. The source code is publicly available and constructed in a well readable, modular way. This enables for a fast implementation of both simple academic test problems and advanced engineering applications. It is also easily extensible to include new physical content.

New user-friendly features:

  • New meta descriptor concept
  • New homogenised lattice Boltzmann method
  • New free energy model
  • Validated wall shear stress functor

New examples:

  • multiComponent/contactAngle2d and multiComponent/contactAngle3d
  • multiComponent/youngLaplace2d and multiComponent/youngLaplace3d
  • multiComponent/microFluidics2d
  • particles/magneticParticles3d
  • particles/settlingCube3d
  • particles/dkt2d
  • porousMedia/porousPoiseuille3d

Minor improvements and developer notes:

  • Restructure example folder
  • Restructure and improve functors
  • New std::shared_ptr-based functor arithmetic to ease memory management and enable functor composition
  • Convenient relative and absolute Lp error norm functors
  • Bug fixed in GnuPlotWriter
  • C++ 14 standard is now mandatory
