It can be used for 3D thermal analyses and mechanical analyses in linear and non-linear statics and dynamics, for machines, pressure vessels and civil engineering structures. Our LBM code allows for a 1D, 2D or 3D domain. The usual CFD practice is, however, to use a variable mesh density, for optimally distributing. It has no particular features to support fuzzy logic but then again, very few - if any - programming languages have such features. Despite the advantages posed by the LBM, no DNS of turbulent pipe ow has been re-ported using LBM. Perhaps it may be useful to understand some of the implementation details about the LBM that are hard to grasp just by reading papers.
