Through the transformation matrix M [25], the fα and fαeq can be projected onto the moment space via m=Mf and meq=Mfeq . [...]the collision step of Equation (1) can be rewritten as: m∗=m−Λ(m−meq)+δt(I−Λ2)S where the I is the unite tensor, and the S is the forcing term in the moment space with (I−0.5...
