Abstract : A linear finite element method for the gas dynamics equations in two dimensions, in conservation form and with a numerical viscosity, is described. Series representations of the integrals of rational functions produced by the conservation form that are suitable for numerical computation are derived. The numerical viscosity is used to smear out shocks. The ordinary differential equations of the method can be integrated by any packaged program designed for systems with a mass matrix. The series representations of the integrals can be used by moving node finite element methods. (Author)
