Synopsis:

The lattice Boltzmann method (LBM) is a modern numerical method allowing the solution of non-stationary partial

differential equations by solving the Boltzmann transport equation for unknown densities of the particle probability

distribution function. The course introduces the basics of the LBM theory, derived equivalent partial differential

equations for an advection-diffusion problem and for the incompressible Newtonian flluid flow, and the basic

properties of the numerical scheme are derived. The exercises are then devoted to the practical implementation and

computations of LBM using the computational infrastructure at FNSPE CTU in Prague, especially with the focus on

GPU computing.
