Tandem

Scalable discontinuous Galerkin code on unstructured curvilinear grids for linear elasticity problems and sequences of earthquakes and aseismic slip. Tandem uses the symmetric interior penalty discontinuous Galerkin (SIPG) method to perform seismic cycle simulations accounting for the complex geometries and heterogeneity of the subsurface. Tandem simulates fault behaviour over multiple seismic events and the intervening periods of aseismic deformation and considers all phases of earthquake faulting, from slow loading to earthquake nucleation, propagation and termination over time scales of milliseconds to millennia in a unified, self-consistent framework, opening new avenues to pursue extreme scale 3D earthquake cycle simulations.
