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)
Text en actes de congrés
Accés restringit per política de l'editorialIn 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 ... -
A dispersion analysis of uniformly high order, interior and boundaries, mimetic finite difference solutions of wave propagation problems
Rojas, Otilio; Mendoza, Larry; Otero Calviño, Beatriz; Villamizar Morales, Jorge; Calderón, Giovanni; Castillo, José; Miranda, Guillermo (Springer, 2024)
Article
Accés obertA preliminary stability and dispersion study for wave propagation problems is developed for mimetic finite difference discretizations. The discretization framework corresponds to the fourth-order staggered-grid Castillo-Grone ... -
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 obertThis 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. ... -
Low dispersive modeling of Rayleigh waves on partly staggered grids
Rojas, Otilio; Otero Calviño, Beatriz; Castillo, José; Day, Steven (2013-10-01)
Article
Accés restringit per política de l'editorialIn elastic media, finite-difference (FD) implementations of free-surface (FS) boundary conditions on partly staggered grid (PSG) use the highly dispersive vacuum formulation (VPSG). The FS boundary is embedded into a ...
