Multi-dimensional earthquake cycle simulation code based on Boundary Element Method with H-matrices.
Features
-
2D and 3D planar/nonplanar faults in a full/half space
-
Rectangular and triangular meshes for 3D problems (require .stl mesh file for triangular mesh)
-
Rate-State friction law
-
Quasi-dynamic approximation using radiation-damping term
-
Hybrid MPI/open-MP parallelization
