MAXW-DGTD

Participants : Loula Fezoui, Stéphane Lanteri [ correspondant ] .

The team develops the MAXW-DGTD software suite for the solution of the 2D and 3D Maxwell equations in the time domain. This software implements a high order discontinuous Galerkin method on unstructured triangular (2D case) or tetrahedral (3D case) meshes [8] . 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 [2] .
