Release Notes: Altair Feko 2018.1.2

Altair Feko 2018.1.2 is available with new features, corrections and improvements. This version (2018.1.2) is a patch release and it should be applied to an existing 2018 installation.

Feko 2018.1.2 Release Notes

The most notable extensions and improvements to Feko are listed by component.


Resolved Issues

  • Fixed a bug that led to an internal error when extracting parts of the CMA matrix.
  • Fixed a bug that caused the reflection and transmission coefficients to be larger than one for PBC models with a dielectric coating.
  • For cable harness modelling, the solver will report all cable signal information when no installation (reference ground represented by triangles or a ground plane) is defined below the cable. Previous versions would not provide information of the return signal in POSTFEKO or in the .out file.
  • Increased the size of the messaging buffer to prevent an error state during an MPI parallel solution.
  • Fixed a bug that caused TR results to be written out incorrectly when multiple TR requests written to .tr files are present inside plane wave loops and results at multiple frequency points are requested.
  • Fixed a bug that resulted in the wrong current being displayed for PBC models, solved using HOBF, that touch the unit cell walls.

Support Components

Resolved Issues

  • Issue a warning instead of an error when importing a binary .stl file when the expected number of elements are not present.
  • Improve error message when reporting XSD file creation during CST NFS import.

WinProp 2018.1.2 Release Notes

The most notable extensions and improvements to WinProp are listed by component.


Resolved Issues

  • RunMS (not RunPro) gave incorrect results for received power in versions 2018.1 and 2018.1.1 due to an incorrect internal conversion from power to field strength. This is fixed.
  • Fixed a bug that resulted in incorrect angles of departure when the height of the transmitter is set relative to the ground's topology.
  • For a MIMO antenna array at the mobile station, if receiving antennas were isotropic without an actual imported antenna pattern, the received power was incorrectly calculated as if there had been only a single isotropic receiving antenna. This has been fixed.
  • Fixed a bug that resulted in the absolute height of a transmitter not being correctly set for urban empirical models.
  • Fixed a bug that resulted in slightly incorrect coherently superposed received power results along a trajectory.
