The Eulerian equations are solved by use of the finite element method FEM in conjunction with the Galerkin method of weighted residuals. The unsteady, nonconservative form of the equations is used to obtain the steady- state solution. Modifications are made in the time integration to improve stability at the cost of sacrificing the transient behavior. Numerical results are presented which compare reasonably well with other numerical solutions and with experimental data for transonic flow over airfoils.
