Nous présentons une approche basée sur les filtres pour calculer les viscosités artificielles pour la méthode des éléments spectraux. Cette procédure est simple et est mise en œuvre sur un grand nombre d'exemples.

We present a filter-based approach to computing artificial viscosities for spectral element methods. A number of applications for this approach are presented.
