  • Int. J. Numer. Meth. Fluids (2007). Vol. 54 (6-8), pp. 639-664

    Abstract
    The Navier–Stokes equations written in Laplace form are often the starting point of many numerical methods for the simulation of viscous flows. Imposing the natural [...]

  • Int. J. Numer. Meth. Fluids (2000). Vol. 32 (1), pp. 1-22

    Abstract
    The iterative solution of linear systems arising from panel method discretization of three‐dimensional (3D) exterior potential problems coming mainly from aero‐hydrodynamic [...]

  • Int. J. Numer. Meth. Fluids (1999). Vol. 29 (5), pp. 605-621

    Abstract
    The finite element method is employed to approximate the solutions of the Helmholtz equation for water wave radiation and scattering in an unbounded domain. A discrete, non‐local [...]

  • Int. J. Numer. Meth. Fluids (1997). Vol. 25 (12), pp. 1347-1371

    Abstract
    This paper presents several numerical results using a vectorized version of a 3D finite element compressible and nearly incompressible Euler and Navier–Stokes code. [...]

  • Int. J. Numer. Meth. Fluids (1995). Vol. 20 (8-9), pp. 1003-1022

    Abstract
    We present a method to assess the stability of pairs of interpolation spaces for mixed formulations. The method is based on a straightforward calculation of the eigenvalues [...]

  • Int. J. Numer. Meth. Fluids (1994). Vol. 19 (1), pp. 1-22

    Abstract
    The modelling of liquid flow in gas‐stirred vessels is described. A simple two‐phase model accounts for the buoyancy effect of bubbles. Friction between liquid and gas [...]

  • Commun. Numer. Meth. Engng (1993). Vol. 9 (9), pp. 729-743

    Abstract
    In a recent paper we presented a data structure to be used with multigrid techniques on non‐homogeneously refined FEM meshes. This paper focuses on the adaptive refinement [...]

  • S. Idelsohn, N. Nigro, J. Gimenez, R. Rossi, J. Marti
    Engineering Computations (2013). Vol. 30 (2), pp. 197-222

    Abstract
    Purpose   – The purpose of this paper is to highlight the possibilities of a novel Lagrangian formulation in dealing with the solution [...]

  • H. Antúnez, S. Idelsohn
    Engineering Computations (1992). Vol. 9 (5), pp. 547-559

    Abstract
    The pseudo‐concentration method is applied to the analysis of transient processes. A simple, easy‐to‐handle model is obtained by keeping an Eulerian description: it [...]

  • E. Barbero, G. Kaufmann, S. Idelsohn
    Optics & Laser Technology (1990). Vol. 22 (1), pp. 17-22

    Abstract
    The fracture behaviour of a four-point bend surface-coated ceramic specimen with a through-the-thickness crack was experimentally investigated. Speckle photography was used [...]
