Implementing a new LB model

While LBPM includes a range of fully-functioning lattice Boltzmann models, the commonly used Bhatnager-Gross-Krook (BGK) model has been deliberately excluded. While the physical limitations of this model are well-known, implementing the BGK model is an excellent way to understand how to implement new LB models within the more general framework of LBPM. In this excercise you will

  • learn “what goes where”

  • don’t modify core data structures (unless you have a really good reason)

  • re-use existing components whenever possible
