Abstract
Frequency-domain finite-difference (FDFD) modeling offers several advantages over traditional timedomain
methods when simulating seismic wave propagation, including a convenient formulation within
the context of wavefield inversion and a straight-forward extension for adding complex attenuation mechanisms.
In this short paper we introduce the FDFD method, develop a simple solver for the scalar
Helmholtz problem, and explore some possible approaches for solving large scale seismic modeling problems
in the frequency domain.
