  • Challenges for time and frequency domain aeroacoustic solvers 

    Angeloski, Aleksandar; Discacciati, Marco; Legendre, César; Lielens, Gregori; Huerta, Antonio (2014)
    Conference report
    Open Access
    The linearized Euler equations (LEE) model acoustic propagation in the presence of rotational mean flows. They can be solved in time [1–3] or in frequency [4–6] domain, with both approaches having advantages and disadvantages. ...
  • Efficiency of high-order elements for continuous and discontinuous Galerkin methods 

    Huerta, Antonio; Angeloski, Aleksandar; Roca Navarro, Francisco Javier; Peraire Guitart, Jaume (John Wiley & sons, 2013-11)
    Article
    Open Access
    To evaluate the computational performance of high-order elements, a comparison based on operation count is proposed instead of runtime comparisons. More specifically, linear versus high-order approximations are analyzed ...
