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)
Open AccessThe 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 ...

Open AccessA 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)
Open AccessRealistic 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 ...

Open AccessMimetic 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 ...
