EM Software & Systems announced the release of FEKO Suite 6.3.
Support for curvilinear meshes in connection with Higher Order Basis Functions (HOBF) has been added for MoM and MLFMM. The curvilinear meshing allows larger elements without sacrificing model accuracy. According to the company, this can result in significant reductions in run-time and memory requirements for some structures. The triangles are second order curvilinear triangles with six vertex points consisting of three corner points and three points in the middle of the triangle edges.
As of September 2013, all users of FEKO Silver, Gold or Platinum licenses have access to all CAD import and export filters. This additional power allows users to import a wide range of models from their native CAD formats. Imported CAD files often require additional work to condition the model into a format where it can be meshed in FEKO. This task has been simplified with the introduction of a set of CAD healing and fixing tools. Examples of these tools include automated fixing of various problems associated with edges and faces as well as a tool to fill complex shaped holes in a model with automatically generated surfaces.
Characteristic modes are now tracked by correlating modes between frequency runs. The mode tracking is based on ordering the modes correctly at each frequency relative to their rankings at the reference frequency (typically the first frequency point). CMA was also extended to support dielectric and magnetic materials with MoM with the surface equivalence principle and apertures with the planar Green's function.
Numerous extensions were made to the cable modeling interface, including selection and snapping to cables in the 3D view, definition of cable paths at a constant distance from model faces, improved searching with the Find cable tool and rectangle selection in the schematic view. The projection of cable network from the 3D view to the cable schematic view has been extended by allowing the user to select the most appropriate projection. The distance between connectors displayed in the schematic view can be varied to prevent overlapping.
