A LATTICE BOLTZMANN MODEL FOR VARIABLE COEFFICIENT ELLIPTIC EQUATIONS

摘要：

A lattice Boltzmann model is proposed to solve elliptic equations with variable coefficient. Compared with the previous model, the present model is a more effective solver to the ellipse equation with variable coefficient, and the ellipse equation is exactly recovered to order O(ω2). The relaxation time r is not fixed and is defined by the coefficient of the equation. The limited numerical results show that the present model is valid for ellipse equations.
