On generalized discrete PML optimized for propagative and evanescent waves
Vladimir Druskin, Murthy Guddati, Thomas Hagstrom
We suggest a unified spectrally matched optimal grid approach for finite-difference and finite-element approximation of the PML. The new approach allows to combine optimal discrete…
A model reduction approach to numerical inversion for a parabolic partial differential equation
Liliana Borcea, Vladimir Druskin, Alexander V. Mamonov +1
We propose a novel numerical inversion algorithm for the coefficients of parabolic partial differential equations, based on model reduction. The study is motivated by the applicati…
A Krylov Stability-Corrected Coordinate-Stretching Method to Simulate Wave Propagation in Unbounded Domains
Vladimir Druskin, Rob Remis
The Krylov subspace projection approach is a well-established tool for the reduced order modeling of dynamical systems in the time domain. In this paper, we address the main issues…
