The one-dimensional elastic wave equation: A finite-difference formulation for animated computer applications to full waveform propagation

elwaspatid: A Python package to compute space-time diagrams for the propagation of elastic waves in 1D rods

“…To the best of our knowledge, there is no open source software available for the computation of space-time diagrams, even if wave propagation software can be found in many scientific fields. Williams et al (1996) proposed a FORTRAN program for the propagation of wavefronts in layered media; this instructional tool is based on finite-difference and outputs the displacement with respect to the spatial variable. Computer Programs in Seismology (Herrmann, 2013) is a set of tools aimed at analysing seismic records.…”
