Major highlights include: Windscreen antenna analysis, generalisation of GO and PBC, FEM modal ports, improvements to CADFEKO geometry creation and manipulation processes. (July 2009) Release of FEKO Suite 5.5 Simple finite large array radiation pattern computation with PBC EMSS is proud to announce the release of FEKO Suite 5.5. As with every release of FEKO, this release includes significant new features in both the CAD interfaces and the solution engine. The following is a highlights list of new features on FEKO Suite 5.5. Users should visit the FEKO Suite 5.5 download area for more complete information. Users with M&S contracts automatically qualify for an upgrade to FEKO Suite 5.5 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. Geometry modelling Improvements to primitive creation * Primitive dialogs open with sensible default values allowing easy placement of objects and a better visual indication of how a parameter affects the primitive. Previews of how a parameter in an object scales its dimensions Bottom width Top depth Height create_preview_1.jpg create_preview_2.jpg create_preview_3.jpg CTRL-SHIFT=CLICK.jpg Snapping * Snapping control has been replaced with auto-snapping by snapping to special points (face centre, edge centre, etc.) close to the mouse pointer. * Snapping also snaps to a clever dynamic grid that resizes to the most suitable size for the current view. Special snapping points Dynamic grid snapping snapping_2.jpg snapping_1.jpg New align tool * A new “align” tool has been introduced to easily place objects on structures - the align tool performs a rotation and a translation as a single transformation and translates from one workplane to another * Ideal for citing an imported antenna model onto a platform, e.g. placing antennas imported to FEKO from Antenna Magus Align tool align.jpg User interface and usability * EM-validation has been extended considerably and it also writes the results to a graphical log where warnings and errors are indicated and explained. * Progress information is indicated while loading and saving of models - this is especially useful for large models. * POSTFEKO has been extended to display axial ratio as both the minor over major axis as well as the major over minor axis.
