Furthering the benefit of modularity is the ability of LBHydra to couple with other applications of the user's choice. This document focuses on some important aspects of the Incompressible LBM (lattice Boltzmann method) analysis type in SimScale in detail. In part because the book introduces lattice-Boltzmann models from lattice-gas cellular automata (as they evolved historically), instead of being directly based on the Boltzmann transport equation (as is more common nowadays). Here is a basic introduction to Lattice Boltzmann models that emphasizes intuition and simplistic conceptualization of processes, while avoiding the complex mathematics that underlies LB models. There are numerous areas for user input and modification in the fluid mechanics simulation, including user-defined material modules, lattice-types and subroutines, thus enabling far more complex simulations.
