SISMO-DGTD

Participants : Loula Fezoui [ correspondant ] , Nathalie Glinsky-Olivier, Stéphane Lanteri.

The team develops the SISMO-DGTD  software for the numerical resolution of the 2D and 3D velocity-stress equations in the time domain. This software implements a high order discontinuous Galerkin method on unstructured triangular (2D case) or tetrahedral (3D case) meshes [13] . The local approximation of the electromagnetic field currently relies on a nodal (Lagrange type) polynomial interpolation method. The underlying algorithms are adapted to distributed memory parallel computing platforms.
