Validation <strong>and</strong> simple applications<br />
Basic algorithm<br />
The proposed numerical code is formulated not in the st<strong>and</strong>ard<br />
way (<strong>and</strong> it is quite inefficient from the computational point of<br />
view).<br />
Even though it is not an efficient implementation, the proposed<br />
formulation is much more similar to any other explicit finite<br />
difference (FD) scheme.<br />
This offers some advantages:<br />
1 it makes easier to implement hybrid schemes, i.e. to mix up kinetic<br />
<strong>and</strong> conventional schemes on the same discretization;<br />
2 it makes easier to compare the LBM scheme with other FD<br />
schemes, mainly in terms of updating rule;<br />
3 it makes easier to implement simple boundary conditions, based on<br />
the concept of local equilibrium.<br />
Anyway the basic sequence of collision <strong>and</strong> streaming step is<br />
preserved.<br />
