    Notes: Solutions of elliptic boundary value problems are obtained with variational formulations by minimization of functionals.Conventional tools of the finite element strategy are emphasized; linear or quadratic approximations on triangular elements, curved iso-parametric elements, Ni shape funtions, Li homogeneous co-ordinates. High speed of computation of the final assembled matrices require the use of the Formal-FORMAC calculus. Illusrations of the finite element method are chosen in the class of the 2d-3d compressible subsonic irrotational flows in a nozzle and around one or several lifting bodies of arbitary shape.

    Compressible viscous flow calculations using compatible finite element approximations (1990)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 11 (1990), S. 719-749 
    Details
    ISSN: 0271-2091

    Notes: We discuss in this paper the numerical simulation of compressible viscous flows by a combination of finite element methods for the space approximation, an implicit second-order multistep scheme for the time discretization and GMRES iterative methods for solving the non-linear problems encountered at each time step. Numerical results corresponding to flows around aerofoils and aerospace vehicles illustrate the possibilities of these methods.

    On the use of subcycling for solving the compressible Navier-Stokes equations by operator-splitting and finite element methods (1988)
    New York, NY [u.a.] : Wiley-Blackwell
    Communications in Applied Numerical Methods 4 (1988), S. 309-317

    Topics: Mathematics , Technology
    Notes: In this paper we discuss the solution of the compressible Navier-Stokes equations by numerical techniques combining finite element approximations, operator splitting for the time discretization and numerical treatment of the nonlinearities by subcycling, which in this context means that we perform on the basic time discretization interval a time integration by a standard numerical scheme for initial-value problems (explicit schemes in this paper). Numerical results for flows around a NACA 0012 aerofoil are presented.
