A stabilized finite element method for the mixed wave equation in an ALE framework with application to diphthong production Guasch Fortuny, Oriol; Arnela, Marc; Codina, Ramon; Espinoza Román, Héctor Gabriel (2016-01)
Open AccessWorking with the wave equation in mixed rather than irreducible form allows one to directly account for both, the acoustic pressure field and the acoustic particle velocity field. Indeed, this becomes the natural option ...
Arnela, Marc; Guasch Fortuny, Oriol; Codina, Ramon; Espinoza Román, Héctor Gabriel (European Acoustics Association (EEA), 2014)
Restricted access - publisher's policyFinite element methods (FEM) are increasingly being used to simulate the acoustics of the vocal tract. For vowel production, the irreducible wave equation for the acoustic pressure is typically solved. However, diphthong ...
Stabilized finite element formulation for the mixed convected wave equation in domains with driven flexible boundaries Guasch Fortuny, Oriol; Arnela, Marc; Codina, Ramon; Espinoza Román, Héctor Gabriel (2015)
Restricted access - publisher's policyA stabilized finite element (FEM) formulation for the wave equation in mixed form with convection is presented, which permits using the same interpolation fields for the acoustic pressure and the acoustic particle velocity. ...
