Hi guys,
I'm in active development of revamping the Numerical Electromagnetics Code and it's front end. The target is to have an end program working which can either pick from a library of known antennas or develop it's own based on your specific parameters (yard size, height restriction, number of support points, materials available, SWR requirement)
Any help would be appreciated; programmers, testers, funding support.
The basic framework is coming together and the program is running in Win32/64 to start. The program can currently open the older .nec extension files perform calculation (outside of DOS) and display the results.
If you have any ideas and have or haven't used 4NEC2 or EzNec before please let me know.
Cheers,
John
Update:
Frequency sweep and SWR added.
Still need more testers. Automated modeling development starts tomorrow.
Cheers,
John
Would it be possible to simulate/design helical coil filters/resonators with this software?
If method of moments simulation would work for you then yes but I don't know the actual accuracy.
John
Nice. I use 4Nec2 a lot. Its a really great free tool. I use it with the nec2 MP refactored code that is way faster than the one that comes as standard. Find it here.
http://users.otenet.gr/~jmsp/I look forward to giving the evolved version a try.
Thanks Hagster. I didn't know this application existed. Optimizing the math and threading will take some time. The newer Ansi C++ 11 math libraries in 64 bit don't perform so well.

Please don't restrict its use to Windoze only. Please ensure it can be run under Wine in Linux, or preferably as a Linux native application.
It would be a shame to downgrade the existing NEC2 codebase, which is available via the usual Linux repositories.
The claims are interesting. A lot of the calculations are sequential from what I can tell. What is the actual performance difference in your experience between the two? Multithreaded and not.
John
Trying not to restrict this to Windows only and keeping the backend multi system compatible. The current compiling system I have with GUI doesn't currently offer Linux but you still should be able to run it from the Windows simulator in Linux.
John
I cant remember the exact speed ups, but i was running a fairly large model on an 8core xeon cpu. The speed difference on that system was pretty significant though.
Still going and getting better. Thanks for the inputs! Looking forward to making this really something special!

Have you compared results with those from MMANA_Gal Basic? I would really be interested to know!
Hi Jim,
No I haven't compared against this software yet.
John
Corrected some segmentation bugs.
Corrected Dipole test model.
There are still some segmentation bugs which need to be worked out. This is Alpha development and there will definitely be issues. The difference can be seen in time between this software and the previous videos showing the original dipole random model.
