Abstract: Using the pressure minimum integral, finite element equations are obtained based on the full potential equation. The blocked structured mesh generation technique, which is suitable for finite element method, is used. The GMRES algorithm for solving global finite element equations is given, the algorithm provides more rapid convergence than iterative line relaxation method. The numerical results of M6 wing in transonic flow are presented, which show that the present method is efficient.
