You found the virtual display of the open-source code tandem presented at vEGU21. Tandem is an open-source code for modelling Sequences of Earthquakes and Aseismic Slip (SEAS).

Tandem implements the Symmetric Interior Penalty Galerkin (SIPG) method using unstructured simplicial meshes. The potential of the SIPG method for SEAS models lies in its geometric flexibility, its high-order approximation spaces, and its natural ability to deal with discontinuities. In this virtual display, we show the verification of high-order convergence of the method, discuss benefits of the SIPG method, and sketch how tandem leverages HPC.
