Multi-spatial-resolution earthquake simulation
AWP-ODC is a world-leading earthquake simulation code, developed at SDSC and SDSU. It currently uses a uniform 3D mesh, that is, same resolution everywhere. One possible improvement is to use finer resolution close to the earth surface, while coarse resolution is used in greater depths.

- Aim of project: To program a two-spatial-resolution version of AWP-ODC, while also studying appropriate interpolation techniques needed for gluing together two regions with different spatial resolutions.
- Approach: Use as starting point a sequential C code, which is a simplified version of AWP-ODC. The master student is to program an enhanced version which incorporates two regions, one with high spatial resolution, the other with coarse resolution. At the same time, different interpolation techniques (between the fine and coarse resolutions) will be implemented and tested.
- Learning outcome: The master student will get hands-on experience with implementing and testing real-world application codes, while learning the basic physical/mathematical principles behind earthquake-induced ground motion. In addition, the student will obtain some knowledge about numerical methods.
- Extra reward: If the master student achieves excellent results with the simplified version of AWP-ODC, he/she will get the opportunity for a short stay in the sunny San Diego, to work with world-leading experts on world-leading parallel computers!
