【Abstract】 A boundary integral element multigrid algorithm of the plan airfoil fluid dynamics is discussed. A format of residue calculus and a formula of functional corrected value are given. A circulation numerical formula which is independent of grid step is obtained. The numerical results show that the multigrid method has faster convergence speed than general iterative method, and results are in good agreement with experimental ones.更多还原
