earthquake.cpp

3D earthquake wave simulation in C++. Python required for visualization only (use requirements.txt to install dependencies).

Tested on Ubuntu 22.04.2 LTS using g++ compiler. I'm not using any fancy C++ features (only used classes), so it should work fine on other systems as well (but, don't blame me if it doesn't)

Drivers

1. 1D simulation: Execute make 1d_sim in the terminal. This will generate the executable file in bin, which can be called as follows: ./bin/sim_1d.out.
2. 3D simulation on a simpler velocity model (saving full 4D solution): Execute make 3d_sim in the terminal. This will generate the executable file in bin, which can be called as follows: ./bin/sim_3d.out.
3. 3D simulation on a simpler velocity model (saving a couple of 3D slices only): Execute make 3d_sim_slices in the terminal. This will generate the executable file in bin, which can be called as follows: ./bin/sim_3d_slices.out.
4. 3D simulation on a complex velocity model (saving a couple of 3D slices only): Execute make 3d_sim_slices_comples in the terminal. This will generate the executable file in bin, which can be called as follows: ./bin/sim_3d_slices_complex.out.

Visualization

Visualization code in viz uses matplotlib and pyplot.

1. view_viz_1d.py: Visualizing 1D simulation using matplotlib.
2. view_viz_3d.py: Visualizing 3D simulation (full) using matplotlib.
3. view_viz_3d_slices.py: Visualizing 3D simulation (slices) using matplotlib.
4. animGen_viz_3d.py: Generates 3D simulation (full) using pyplot and saves it as mp4.
