Summary
A simple Finite Element scheme is proposed for the solution of the full potential equation of gasdynamics which is based on a variational principle stating that the static pressure forms a minimum relief with respect to prescribed boundary conditions. The introduction of an artificial density allows for the computation of transonic flow past aircraft components of engineering interest. Selected results will show benefits and present limitations of the method.
