A Seismic Wave Propagation Code by Parallel Finite Difference Method

OpenSWPC -- An Open-source Seismic Wave Propagation Code

Corresponding Author: Takuto Maeda

Description

This software simulate seismic wave propagation by solving equations of motion with constitutive equations of elastic/viscoelastic medium by finite difference method (FDM) under message passing interface (MPI) environment in 3D and 2D (P-SV or SH) media.

This package also provides a set of tools for visualizing/converting simulation output.
