./ham/nec2c, Numerical Electromagnetics Code in C

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 1.3.1, Package name: nec2c-1.3.1, Maintainer: pkgsrc-users

nec2c is a translation of the NEC2 FORTRAN source code to the C
language. The translation was performed mostly "by hand" and a
lot of modifications to the original program were introduced in
order to modernize the NEC2 and to remove as many built-in limitations
as possible. The attendant SOMNEC program was also translated to
C and incorporated in nec2c as a function so that Sommerfeld ground
solutions are a part of the program.

Log message:
(ham/nec2c) Updated 1.3 to 1.3.1

  Version 1.3.1: Fixed a bug in the fbar() in somnec.c reported by
  Ward Harriman, AE6TY, that caused corrupt results with wire dipoles
  close to ground and while using Sommerfeld/Norton approximation.

Log message:
all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Log message:
Add SHA512 digests for distfiles for ham category

Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden).  Existing SHA1
digests retained for now as an audit trail.

Log message:
Update nec2c 1.1 to 1.3
-----------------------
  Version 1.2: Fixed four issues (defects) reported by Coverity Scan
  (https://scan.coverity.com/). Two of those were in the somnec
  functions and I suspect that they did effect the calculations in
  the rom1() and gshank() functions, at least under some circumstances.
  Unfortunately the original Fortran source (somnec.for), as the rest
  of the NEC2 Fortran source, is extremely difficult to read so I am
  not able to confirm the impact of those reported defects.

  Version 1.3: Revised the fix of one issue reported by Coverity Scan,
  as on more detailed comparison with the original Fortran code, it
  seems the original changes (in the ROM1 function in SOMNEC) were
  not correct. Unfortunately I cannot verify the correctness of the
  above fixes, as nec2c does not print out SOMNEC output files.
