The GdfidL Electromagnetic Field simulator
GdfidL computes electromagnetic Fields in
3DStructures using parallel or scalar Computer 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,
 QValues 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.
 For Eigenvalue Computations, GdfidL allows periodic Boundary Conditions
in all three cartesian Directions simultaneously.
 GdfidL runs on parallel NuMA Systems. GdfidL also runs on
Clusters of Workstations.
Availability
GdfidL is available for almost every hardware platform.
GdfidL only runs on UNIXlike operating systems.
 AIX on IBMPower.
 Linux or Solaris on AMD64, and whatever Intel calls the architecture now (I64).
 Tru64 or Linux on Alpha.
 PHASED OUT: HPUX on PARISC. Last Version of 199x.
 PHASED OUT: IRIX on SGIMIPS. Last Version 199x.
 PHASED OUT: Linux on IA64, Itanium. Dead. Last version of 2006.
 PHASED OUT: Solaris on SPARC. Dead. Last version 200x.
 and more. Whatever you want,
Price
The Price for a one Year License for the single Machine Version of GdfidL
(including Support) starts at
