we primary study parallel algebraic additive Schwarz preconditioning technique for the Schur complement in the context of frequency domain electromagnetic wave propagation problems. For that purpose, the system of 2D and 3D time-harmonic Maxwell equations in first order (or mixed) form is discretized using a discontinuous Galerkin method...

We present a parallel domain decomposition method based on a hybrid direct-iterative solver for 3D modelling of visco-acoustic waves in the frequency domain. The modelling method was developed as a modelling engine for frequency-domain full waveform inversion. Frequency-domain seismic modelling reduces to the solution of a large and sparse...
