Spectral analysis of high order continuous fem for hyperbolic pdes on triangular meshes: influence of approximation, stabilization, and time-stepping

HIGHLIGHTS

  • who: Sixtine Michel from the CEA CESTA, avdes Sabliu00e8res, Le Barp, France have published the research: Spectral Analysis of High Order Continuous FEM for Hyperbolic PDEs on Triangular Meshes: Influence of Approximation, Stabilization, and Time-Stepping, in the Journal: (JOURNAL)
  • what: (2) One of the main objectives of this paper is to identify strategies to build (linearly) stable fully explicit high order continuous finite element schemes to discretize on triangulations of the spatial domain. Although other definitions are possible, the authors evaluate the scaling parameter in the stabilization as u03c4 f=u03b4 h 2f u2207u . . .
