In this paper, analytic relations between the macroscopic variables and themesoscopic variables are derived for lattice Boltzmann methods (LBM). Theanalytic relations are achieved by two different methods for the exchange fromvelocity fields of finite-type methods to the single particle distributionfunctions of LBM. The numerical errors of reconstructing the single particledistribution functions and the non-equilibrium distribution function bymacroscopic fields are investigated. Results show that their accuracy is betterthan the existing ones. The proposed reconstruction operator has been used toimplement the coupling computations of LBM and macro-numerical methods of FVM.The lid-driven cavity flow is chosen to carry out the coupling computationsbased on the numerical strategies of domain decomposition methods (DDM). Thenumerical results show that the proposed lifting relations are accurate androbust.
