Fig. 2From: OpenSWPC: an open-source integrated parallel simulation code for modeling seismic wave propagation in 3D heterogeneous viscoelastic mediaAn example of a nearly constant Q model using three Zener bodies (bold black curve), considering a constant Q (=100) in the frequency range between 0.02 and 2Â Hz. Dotted lines show the contributions from three Zener bodiesBack to article page
