Dispersion-corrected compact finite difference discretizations for the elastic Helmholtz equation in two and three dimensions
Rachel Yovel, Eli Turkel, Eran Treister
We develop a family of compact, dispersion-corrected marker-and-cell (MAC)-based finite-difference discretizations for the elastic Helmholtz equation. While dispersion correction i…
Attention-based hybrid solvers for linear equations that are geometry aware
Idan Versano, Eli Turkel
We present a novel architecture for learning geometry-aware preconditioners for linear partial differential equations (PDEs). We show that a deep operator network (Deeponet) can be…
Fast meta-solvers for 3D complex-shape scatterers using neural operators trained on a non-scattering problem
Youngkyu Lee, Shanqing Liu, Zongren Zou +5
Three-dimensional target identification using scattering techniques requires high accuracy solutions and very fast computations for real-time predictions in some critical applicati…
Fourth order accurate compact scheme for first-order maxwell's equations
Idan Versano, Eli Turkel, Semyon Tsynkov
We construct a compact fourth-order scheme, in space and time, for the time-dependent Maxwell's equations given as a first-order system on a staggered (Yee) grid. At each time step…
