(July 2008)
CADFEKO symmetry specification
EMSS is proud to announce the release of FEKO Suite 5.4.  As with every release of FEKO, this release includes significant new features in both the CAD interfaces and the solution engine.  This release also introduces FEKO's new licencing scheme to exploit multicore processors to their full potential.  The following is a highlights list of new features on FEKO Suite 5.4.  Users should visit the FEKO Suite 5.4 download area for more complete information.  Users with M&S contracts automatically qualify for an upgrade to FEKO Suite 5.4 and can download the appropriate installation from this download area.  Readers without M&S contracts are invited to contact their local distributor to arrange an evaluation licence.
Improved specification of symmetry and excitations in CADFEKO
Symmetry may be specified directly in CADFEKO.  The full 3D model is constructed and no special geometry modifications are required to exploit geometric, electric or magnetic symmetry planes.  More information...
Most excitation types and options can now be specified in CADFEKO, e.g. waveguide excitations, aperture excitation, spherical modes, impressed current excitations, edge excitations with respect to a UTD plate or infinite ground plane.
Waveguide excitation has been simplified with geometry-independent reversal of the specification of propagation direction and the option to let FEKO automatically compute and excite the primary propagating mode for any waveguide shape.
Periodic boundary conditionsInfinite general periodic boundary conditions in 1- and 2-dimensions have been added with an implementation that includes skewed lattice capabilities.  Applications of periodic boundary conditions include frequency selective surface characterisation, large array analysis etc.  More information...
General non-radiating networksConnection options for general non-radiating networks and transmission lines have been extended so that they may be interconnected (cascaded) or connected to wire segments, vertices or edges in the model.  Loads and excitations may also be applied to the ports of networks.  More information...
General non-radiating Networks and Transmission lines are supported in CADFEKO.
CAD import/exportThe CAD import process has been made more robust and provides a number of new features for importing of meshes and geometry and the identification and fixing of errors that my exist in imported model elements.
CAD export filters for ACIS, STEP, IGES, Catia v4 and v5 have been added (optionally purchased separately from FEKO).  
An import module for the import of DXF CAD geometry is available (optionally purchased separately from FEKO).
Solution methodsWaveguide excitations may be used in a model where Physical Optics (PO) approximations are used.
Parallelisation of the FEM/MoM and GO/MoM hybrid techniques (for shared and distributed memory platforms and multi-core systems).
Improved interfacing with other tools, e.g. a new interface to CRIPTE from ESI Group for cable-coupling applications, and extension of existing interfaces (e.g. TICRA spherical modes, NASTRAN, etc.)
Improved efficiency when computing near- and far-fields in a parallel solution using a small number of parallel processes.
OptimisationOptimisation with masks and parameter constrains is supported.  This allows more flexible control of the optimisation process and better specification of optimisation goals.  More information...
Farming out of optimisation iterations is supported (i.e. con-current solution of optimisation steps on different processors).
Licencing and platforms
Changes to the licencing policy to optimally use multi-core processors. Licencing is now based on number of CPUs as opposed to number of cores or processes.  More information...
Direct support for queueing systems (LSF, PBS and others), including integration into Windows CCS (compute cluster server).
Porting to the IBM AIX PowerPC architecture.
