I am a beginner in CFD world, however I know the basics of each blackbox of any commercial software. but while I take an overview of xflow software I did not see any mesh generation and while I was searching about that I found that, this software is based on the Lattice Boltzmann method, thus I want why there is no meshing and also what is the relation between the mesh and that method.

thank you
