Altair HyperWorks FEKO v14.0.41
FEKO New Features
This is the first release of FEKO within Altair HyperWorks and HyperWorks version numbering is adopted.
The main features of this release with HyperWorks 14.0 are:
Curvilinear meshes for wires
Support for curvilinear mesh segments has been added for the method of moments (MoM) and multilevel fast multipole method (MLFMM). Curvilinear mesh segments allow a more accurate representation of curved wires than linear elements. When meshing a complex, curved model, the same geometrical accuracy can be achieved with fewer curvilinear segments than with linear segments. This is beneficial, since a mesh with fewer unknowns results in an overall reduction of computational requirements. Curvilinear segment meshing is the new default setting for meshing wires. Curvilinear segments are supported in various ways:
Curvilinear segments may be imported from NASTRAN, ANSYS CDB and Abaqus file formats.
Curvilinear segments may be exported to NASTRAN, Gerber and AutoCAD DXF file formats.
The currents on curvilinear segments can be displayed in POSTFEKO.

Better geometrical representation. Same accuracy with fewer unknowns.
HOBF for hybrid MoM/UTD and hybrid MoM/RL-GO
Higher order basis functions (HOBF) can now be used for the MoM regions in the following hybrid techniques:
MoM hybridised with ray launching geometrical optics (RL-GO)
MoM hybridised with the uniform theory of diffraction (UTD)
HOBF is supported for curvilinear mesh elements, which allow complex, curved geometry to be represented accurately by coarse meshes containing large triangles. The hybrid solvers in FEKO are applicable to electrically large problems. With the support of HOBF in the MoM regions in the hybrid Mom/RL-GO and MoM/UTD techniques, a reduction in memory and run-time can be achieved for these computationally expensive problems.

Using 16 triangles (order 3.5) instead of 1232 RWG (first order) triangles for a circular subreflector (radius=one wavelength).
Finite difference time domain extensions
Multiple configurations in a single model.
Perfect magnetic conductor (PMC) boundary conditions (in addition to open and perfect electric conductor (PEC) boundaries).
Zero impedance loads.
Ports without sources or loads. Such ports are treated as short circuits (similar to the MoM).
An intrinsic wire radius definition. The user does not need to specify a wire radius, in which case the radius will be determined by the solver.
OpenMP parallelisation for multicore machines
