A generalised time-split finite element method is developed to solve Navier-Stokes equations for compressible flow. The method handles the non-rectangular elements in the physical domain by transforming the governing equations to the generalised space (+69, eta ). Such an approach is found to be superior to the use of an isoparametric formulation. The method makes use of the group formulation which offers considerable advantages over a formal finite element approach. The generalised time-split finite element method is applied to laminar flow past symmetric and asymmetric trailing edges. Imposition of non-reflecting boundary conditions is another feature of the present work. A procedure called the 'Variable Sweep' cycle is described and is found to contribute significantly towards saving in execution time.
