get_stencil
(name, ordering='walberla')¶ Stencils are tuples of discrete velocities. They are commonly labeled in the ‘DxQy’ notation, where d is the dimension (length of the velocity tuples) and y is number of discrete velocities.

name – DxQy notation
ordering – the LBM literature does not use a common order of the discrete velocities, therefore here different common orderings are available. All orderings lead to the same method, it just has to be used consistently. Here more orderings are available to compare intermediate results with the literature.
