The GdfidL Electromagnetic Field Simulator
GdfidL computes electromagnetic Fields in
3D-Structures. It is optimised for Multi-Core Systems and Clusters of such Systems.
The Postprocessor computes from these Fields eg.
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.
- Scattering Parameters,
- Wake Potentials,
- Q-Values and Shunt Impedances.
- 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
- Wakepotential Computation of Collimator-like Devices applying a
- 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.
GdfidL is available for almost every hardware Platform.
GdfidL only runs on UNIX-like operating Systems.
The Price for a one Year License for the single Machine Version of GdfidL
(including Support) starts at
10.000 Euros for Linux-on-AMD64 Computers.
The Price for a one Year License for the Cluster Versions starts at
20.000 Euros for Linux-on-AMD64 Clusters.
Access to powerful Servers where GdfidL is installed on costs
9.000 Euros per Year.
