We introduce a mimetic finite‐difference method for modeling acoustic‐wave propagation in complex media. This method incorporates fundamental physical principles in the discretization of the acoustic‐wave equation. The free surface boundary conditions are naturally embedded into the scheme. Unstructured polygonal meshes are used to represent complex shapes of interfaces, irregular and fine inclusions, and complex surface topography. Locally refined meshes can be employed in regions with different wave speeds. We numerically demonstrate that the new method can accurately simulate complex wave phenomena.Permalink: https://doi.org/10.1190/1.3059298FiguresReferencesRelatedDetailsCited BySolving the tensorial 3D acoustic wave equation: A mimetic finite-difference time-domain approachJeffrey Shragge and Benjamin Tapley13 June 2017 | GEOPHYSICS, Vol. 82, No. 4A new mimetic scheme for the acoustic wave equationJournal of Computational and Applied Mathematics, Vol. 295 SEG Technical Program Expanded Abstracts 2008ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2008 Pages: 3713 publication data© 2008 Copyright © 2008 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 15 Dec 2008 CITATION INFORMATION Konstantin Lipnikov and Lianjie Huang, (2008), A mimetic finite‐difference method for acoustic‐wave modeling on arbitrary meshes, SEG Technical Program Expanded Abstracts : 2067-2071. https://doi.org/10.1190/1.3059298 Plain-Language Summary PDF DownloadLoading ..." @default.
