    • A comparative study of two compact finite difference methods: standard vs. mimetic 

      Córdova, Luis Joaquin; Rojas, Otilio; Otero Calviño, Beatriz; Castillo, José (Sociedad Venezolana de Métodos Numéricos en Ingeniería, 2014)

      In this work, we implement two fourth-order compact finite differences (CFD) methods and use them to model wave propagation on a elastic string. The formulation of the first method employs the standard implicit CFD constructed ...

    • Alternating direction implicit time integrations for finite difference acoustic wave propagation: parallelization and convergence 

      Otero Calviño, Beatriz; Rojas, Otilio; Moya, Ferrán; Castillo, José (Elsevier, 2020-06-15)
      Article
      Accés obert
      This work studies the parallelization and empirical convergence of two finite difference acoustic wave propagation methods on 2-D rectangular grids, that use the same alternating direction implicit (ADI) time integration. ...

    • Mimetic Operators for Seismic Exploration 

      de la Puente, Josep; Rojas, Otilio; Ferrer, Miguel; Kormann, Jean (European Association of Geoscientists and Engineers, 2016-05-31)
      Text en actes de congrés
      Accés obert
      Mimetic operators are a kind of discrete operators which, on staggered grids, can accomplish "mimetic" properties analogous to their continuous counterparts. Furthermore, they can attain identical convergence order everywhere ...
