The GdfidL Electromagnetic Field Simulator

GdfidL computes electromagnetic Fields in 3D-Structures. It is optimised for Multi-Core Systems and Clusters of such Systems.

GdfidL computes

Time dependent Fields in lossfree or lossy Structures. The Fields may be excited by
- Port Modes,
- relativistic Line Charges.
Resonant Fields in lossfree or lossy Structures.

The Postprocessor computes from these Fields eg.

Scattering Parameters,
Wake Potentials,
Q-Values and Shunt Impedances.

Features

GdfidL computes only in the Field carrying Parts of the computational Volume. For eg. Waveguide systems, this makes GdfidL about three to ten times faster than other Finite Difference based Simulators.
GdfidL uses generalised diagonal Fillings to approximate the Material Distribution. This reduces eg. the Frequency error by about a Factor of Ten.
Wakepotential Computation of Collimator-like Devices applying a 3D-Napoly Integration.
Wakepotential Computation in a co-moving Mesh.
For Eigenvalue Computations, GdfidL allows periodic Boundary Conditions in all three cartesian Directions simultaneously.
GdfidL is optimised for Multi-Core Systems, especially NuMA Systems. GdfidL also runs on Clusters of Workstations.

Availability

GdfidL is available for almost every hardware Platform.
GdfidL only runs on UNIX-like operating Systems.
