FEKO Suite 5.2 release

Major highlights include: Complete problem setup and solution control in CADFEKO, Re-meshing, Excitation in the FEM region, Coaxial cable analysis. (August 2006)

User Interface

  • The entire EM problem is now defined in CADFEKO. Not only is CADFEKO used to define the geometry but also the solution settings (e.g. including medium properties, coatings / losses, the model unit, sources, loads and calculation requests (near-fields, radiation pattern etc.).) EDITFEKO is required only for advanced solution control (e.g. multiple frequency loops, several sources and multiple solutions) and symmetry settings. EDITFEKO is fully maintained for backwards compatibility with existing models.

  • Remeshing: Tetrahedral and triangle meshes can be refined (coarser or finer) in CADFEKO without a need for the underlying geometry

  • CADFEKO can now archive different versions of the model as it is developed. This is useful to retrieve prior models.

  • ABAQUS: (*.inp) mesh import supported

  • Single precision solution: The solution can now be specified to use single precision, reducing the required memory by 50 percent.


Kernel

  • Transmission line modelling: Built-in support for simple transmission line (TL) modelling so that the currents and voltages induced at the cable terminals, due to an external source, can be calculated directly. Several pre-defined shielded coaxial cable types, of which the transfer impedance is known, are readily available in FEKO (e.g. RG-58). User defined cable types are also supported.

  • Ideal receiving antenna (dual to AR card). The AR card has been available to read an arbitrary radiation pattern (measured data, separate computation with FEKO or another package) and use this as an ideal transmitting antenna. The dual to this, a receiving antenna, is now provided (RA card).

  • Rotation angle for circular and coaxial waveguide mode excitation. It is now possible to specify a rotation angle for each mode excitation (AW card) e.g. two TE11 modes can be excited with a 90 degree rotational difference between them.

  • Better control over S-parameter computation (SP card). New flags are available which allow better control over the way FEKO deals with the load impedances at the ports.


Hardware Support

  • Parallel versions of FEKO for Linux on the IA32, EM64T, AMD64, and IA64 platforms are now also available in connection with Intel MPI. Intel MPI supports interconnects such as Myrinet or Infiniband, but also the traditional Ethernet (and GigabitEthernet).


Licencing

  • Support for multiple redundant floating licence servers.
