Added

  • Update hint: at start Hertzon asks GitHub in the background for the newest release. When it is newer
    than the running version, the Message Manager and the status bar say "Hertzon X is available" with a link
    to the release page. The start does not wait for it, and without network nothing is shown. Switch it off in
    Tools > Options > General (or with the environment variable HERTZON_NO_UPDATE_CHECK=1).
  • File > Open Example: lists the example projects shipped with Hertzon (patch antenna, hairpin filter,
    waveguide post, RCS models, ...) and opens the chosen one as an untitled copy. The example files stay
    unchanged; Save asks for a new file name (in the Documents folder) and an analysis asks to save first.

Changed

  • Field plots on helper sheets follow the sheet: a field plot on a non-model object is drawn again on
    the new shape when the object is moved, resized or otherwise changed. The solution stays valid, as
    non-model objects are not part of the solve.

Fixed

  • Clean edges for field plots on drawn planes: the plot on a non-model sheet now ends exactly on the
    sheet's outline, also for round outlines and sheets with holes. Before, whole cut triangles stuck out over
    the edge or were missing next to it.
  • Animate no longer resizes the 3D view: the player bar under the view asked for about 1100 pixels of
    width, so starting an animation squeezed the model tree and widened the 3D view to the same size every
    time (and it stayed so after closing the player). The bar now fits the view as it is; long texts in it
    are cut instead.
  • RCS and far fields of scattering problems with AURA refinement: the far-field surface (the box
    between scatterer and radiation boundary) lies inside the air, and the direction of its normals was taken
    from a neighbouring element. After an AURA pass part of them pointed inwards, so the monostatic RCS
    jumped by several dB from pass to pass (NATO sphere: between -6.5 and +3.5 dB from the Mie value, and
    the scattered power through the box fell below zero). The normals now point away from the box centre.
    Local (Delaunay) and Remesh were not affected.

Windows installer (Hertzon-Setup-*.exe) and Linux package (Hertzon-*-linux.tar.gz).

Hertzon is built on EMerge, the open-source FEM solver by
Robert Fennis, which provides the finite-element core.
