Discuss SW4. Get help with installation. Ask questions about running the code. Start a discussion on new and/or existing features. For help, see also GitHub Issues and Discussions:

- [GitHub - geodynamics/sw4: SW4 (Seismic Waves, 4th order) implements substantial capabilities for 3-D seismic modeling, with a free surface condition on the top boundary, absorbing super-grid conditions on the far-field boundaries, and an arbitrary number of point force and/or point moment tensor source terms.](https://github.com/geodynamics/sw4)
