EZNEC Pro+ v. 7.0 Update List
This is a list of changes or fixed problems in each
EZNEC Pro+ v. 7.0 update. Updates apply to both
EZNEC Pro/2+ and EZNEC Pro/4+
v. 7.0 unless otherwise noted.
To determine the version of EZNEC Pro+ v. 7.0 you are using, open the Help menu
and select "About EZNEC".
- 7.0.4
- Added the ability to model wire insulation loss (loss tangent) when running NEC-5.
This does not require any change to or replacement of the external NEC-5 program.
-
- Corrected incorrect outer ring value on 2D Ground Wave, Linear Maj, Min, and circular polarization
plots when decimal delimiter is a comma with all calculating engine types except internal
NEC-2.
-
- Program would crash if not all wires have the same loss and one or more is deleted, then Src Dat clicked.
Some inaccuracies might have occurred also if wires were added or moved, since losses might be
assigned to incorrect wires.
-
- Added wire insulation loss to items triggering "Model contains loss" message at bottom of
main window when running a 3D plot.
-
- Program would crash when using NEC-5 if the model contained a transmission line with VF
less than 1, length specified as actual distance, and one port connected within 1/2 segment
length of end 1 of wire 1.
-
- In the (Y parameter) Networks window, the Port 2 Act value shown was really the Port 1 Act value.
Only the display was in error.
-
- Updated the manual.
-
- Reading and Writing .NEC Format Files:
- Loss tangent wasn't being read from IS cards when using NEC-4.2.
-
- IS cards (including loss tangent) are now read and translated regardless of the calculating
engine currently in use. But they are still written only when using an NEC-4.2 calculating
engine. See the EZNEC manual 'Working with NEC Format Files' topic for more information.
-
- Corrected reading and writing Antenna Notes as CM lines.
-
- Added additional info notes ('CM !') when writing.
-
- Properly limited length of CM card lines when writing.
-
- Added segments to auxiliary wires when writing with NEC-2 or -4.2 to avoid "on open end"
messages if the resulting .NEC format file was opened in EZNEC.
-
- Most EX4 and EX6 cards in .NEC format files are now recognized as current sources
when reading regardless of the NEC format type (2, 4.2, or 5) used when saving or
opening.
- 7.0.3
- Added the ability to model wire insulation (except loss tangent) when running NEC-5.
This does not require any change to or replacement of the external NEC-5 program.
-
- The total peak near field, shown when Special Option PeakNFVals = True, was not
correct under some conditions.
-
- When using the NEC-2 calculating engine, results for total and maximum near field
were not correct under some conditions.
-
- Program would crash when opening Utilities/Ground Info when some ground parameters
were extreme.
-
- When using the NEC-2 calculating engine with a model having one or more wires with
loss and not all wires having the same loss parameters, errors could occur when
running an SWR or Frequency Sweep. Errors were generally minor except when the
model contained loads, in which case some or all loads were excluded from the
analysis at all frequency steps except the first one.
-
- Updated the manual.
-
- 7.0.2
- Added phase information to the Far Field table. Added Special Option FFPhase = off
to disable it if desired.
-
- When using an internal or external NEC-4.2 calculating engine, recalculation wasn't
reset when changing between High and Extended Accuracy ground.
-
- EZNEC Pro/4+ only:
Recalculation wasn't reset when changing to and from the internal NEC-4.2
calculating engine unless some other description change was also made.
-
- Updated the manual.
-
- 7.0.1
- This was the initial EZNEC Pro+ v. 7.0. release.
