Nested domain decomposition with polarized traces for the 2D Helmholtz equation
Leonardo Zepeda-Núñez, Laurent Demanet
We present a solver for the 2D high-frequency Helmholtz equation in heterogeneous, constant density, acoustic media, with online parallel complexity that scales empirically as $\ma…

A short note on the nested-sweep polarized traces method for the 2D Helmholtz equation
Leonardo Zepeda-Núñez, Laurent Demanet
We present a variant of the solver in Zepeda-Núñez and Demanet (2014), for the 2D high-frequency Helmholtz equation in heterogeneous acoustic media. By changing the domain decompos…
