DGTD
3D Electromagnetic Simulator
DGTD tackles the most challenging classes of nanophotonic simulations with a finite element Maxwell’s solver based on the discontinuous Galerkin time-domain method. When accuracy is mission critical, DGTD provides superior performance, independent of geometry complexity, within a design environment specifically engineered for multiphysics simulation work flows.
