    • A mimetic wave equation discretization with absorbing boundary condition: Formulation and application 

      Solano-Feo, Freysimar; Guevara-Jordan, Juan; Rojas_Ulacio, Otilio; González-Ramirez, Carlos; Otero Calviño, Beatriz (2016)
      Conference report
      Open Access
      The cornerstone of mimetic finite differentiation (FD) is that discrete gradients and divergences, in combination with a novel boundary flux operator satisfies an approximation to the Gauss–Divergence theorem. In this ...
    • A new mimetic scheme for the acoustic wave equation 

      Solano, Freysimar; Guevara-Jordan, Juan; Rojas, Otilio; Otero Calviño, Beatriz; Rodriguez, R. (2016-03-15)
      Article
      Open Access
      A new mimetic finite difference scheme for solving the acoustic wave equation is presented. It combines a novel second order tensor mimetic discretizations in space and a leapfrog approximation in time to produce an explicit ...
    • A performance analysis of a mimetic finite difference scheme for acoustic wave propagation on GPU platforms 

      Otero Calviño, Beatriz; Frances, Jorge; Rodriguez Cruz, Robert; Rojas, Otilio; Solano, Freysimar; Guevara-Jordan, Juan (2017-02-01)
      Article
      Open Access
      Realistic applications of numerical modeling of acoustic wave dynamics usually demand high-performance computing because of the large size of study domains and demanding accuracy requirements on simulation results. Forward ...
    • Modeling seismic wave propagation using staggered-grid mimetic finite differences 

      Solano, Freysimar; Guevara-Jordan, Juan; González, Carlos; Rojas, Otilio; Otero Calviño, Beatriz (2017-04-12)
      Article
      Open Access
      Mimetic finite difference (MFD) approximations of continuous gradient and divergente operators satisfy a discrete version of the Gauss-Divergente theorem on staggered grids. On the mimetic approximation of this integral ...
