FEKO Suite 5.3 release

Major highlights include: Re-design and re-implementation of optimisation process, inclusion of non-radiating network analysis, Geometrical Optics (GO) for the analysis of electrically large dielectric bodies. (July 2007)
FEKO Suite 5.3 release

FEKO Suite 5.3

User Interface

  • OPTIMISATION: Complete re-design and re-implementation of the optimisation process and workflow.
  • Stand-alone command-line driven tool for CAD model re-evaluation and meshing.
  • POSTFEKO GUI available on the 64-bit x86_64 platform.
  • Selective importing from existing CADFEKO models.
  • GID mesh import.

Kernel

  • Geometrical Optics for dielectrics: A new method is available for the analysis of large dielectric structures, particularly for lens antenna applications.
  • General non-radiating networks: Multiple cascaded general multiport networks (based on S- , Y-  and Z- matrix representations) may be included in the FEKO model. Current interaction is taken into account at the network-geometry connection points.
  • Fast near-field calculations for the MLFMM: Dramatic reduction in time required for computation of the near-field at many points for large models.
  • Waveguide port excitation available on models that include dielectric parts: Available for MoM/SEP or FEM models or where the CFIE (combined field integral equation) is used on metallic objects.
  • UTD extended: Provision for connection of multiple plates at a single edge.
  • Support for the indexed point-arrays in EDITFEKO: Expansion to allow for point-array and variable-array based definition of polygon and polygonal plate geometry primitives in scripted geometry definitions with no limitation on the number of points used.

  • Improved parallel MLFMM efficiency: Run-time improvement due to load balancing and improved parallel communication schemes.

  • Improved memory allocation on 32-bit Windows operating systems: The maximum memory allocation has been expanded by modification of the Windows DLL handling code.

Licencing

  • Extension of the concept of a ”preferred” licence to node-locked licences.

  • Provision for the usage of a node-locked licence on a computer when network / nameserver access is not available: When a licence file containing mixed floating/node locked licences is used, network access is no longer required.

  • More robust automatic check-in of checked-out licences
