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.
Hi, given the calculation efficiency of SW4 and its ability to consider the ground layers and topography in a relatively huge region, it's a powerful and useful tool to simulate the whole process of an earthquake.
However, I want to reduce the size of the region which may be 100km×100km×50km, containing the rupture, to a relatively small one without this rupture which size may be 5km×5km×5km.
Based on such a demand, I hope a seismic wave can be injected into this smaller region. As a result, I can simulate the propagation of a seismic wave in this region with less computation cost.
So, are there any measures to input a seismic wave at the boundaries of the SW4 model?

Thanks a lot!
