Therefore, the installation and configuration of dynfd3dcuda and CGFDM3D-EQR are not repeated here. In practice, a new directory should be created under ../dynfd3dcuda/jobs/ as the job directory (e.g., ../dynfd3dcuda/jobs/temp). First, download the S-wave velocity data, convert it to the 100.2_22.2.mod format, and name it media02. Then, run getmedia.py to generate the medium file media3d_0.2.nc. Next, copy the init_stress.nc file corresponding to the target model into the same directory as fault_coord.nc (i.e., ../dynfd3dcuda/jobs/temp). Submit and run the dynfd3dcuda program. After the simulation completes, run source.m to obtain the strong ground motion source, move it to the /source/ directory of the CGFDM3D-EQR program, and finally submit and run CGFDM3D-EQR.
