NEC computor programs
 

How confident are you regarding the validity of your computor
program that you designed or purchased. If your program
will handle multi variable dimensions to pursue a desired
course of design then insert a program where all dimensions
are variable. But first write down what you expect from your program.
If the computor finds you to be correct then you surely are an expert.
But what if it doesn't? Do you want to learn from it or keep quiet.?
What mettle of man are you?
Hint keep one dimension constant to prevent
the program from going AWOL

These computor programs that are being offered by many is really
bothering me. Since the early days of antenna programming where there
was oversight over the accuracy of programs and where it was released
to the public there has been no oversight.
That means that anybody can sell a computor program with algorithms
that are faulty and even be granted a patent. Thus amateurs and
professionals are now buying antenna computor programs on pure trust!
Who would have believed that science would come to this, pure trust
and put themselves at risk.
Now I have provided the basis of a totally new series of antennas
so can I generate an algerithm that supports my claim and sell it to
the masses? Yes I sure can as long as I protect the generation of
Yagi's there is nobody out there that can challenge me.
And these programs could then end up being used by Governments as they
are not interested in checking the underlying facts as that is for a
beurocrat to follow up on. The present crop of programs
made around unknown and unchecked algorithms do not in the main
allow for comparisom checks against other programs and frankly they
all differ in their results which we all blow away since so much is
based on empirical analysis and as such one will vary from another. I
put out a challenge for any computor program regardless of what
algarithms were used to come out with the same design using variables
such that erronius algorithms could not be protected btu programmers
need the money and will not agree to that and the government will buy
it anyway.
I stated earlier that in a way the yagi put science back a few decades
and the yagi designs are perpetuating this dragging.
When will those who have the power step into this morass and clear
things up such that we can move towards accuracy?
When will we have programs that totally agree with each other such
that the likes of W4RNL doesn't have to alert us to areas where we
must fudge a bit? If the power of a lashing tongue is always able to
repell the advance of science we are indeed in a sorry state. Who
amongst you can voutch for the veracity or accuracy of the program
that you put your trust into via personal
contact of all the intricancies that the programmer placed into it
without oversight?

NEC-2 has been in constant use for about 30 years, and it's used daily
to design antennas for a vast multitude of purposes -- antennas which
are used by millions worldwide. It has been shown, over and over, to to
agree closely with measured results. This shouldn't be any big surprise,
since it uses fundamental equations which have been known and verified
for over a century. There are, of course, some limitations to its
abilities, and situations where it gives erroneous results. The vast
majority of these have been found and well documented. And like any
modeling system, computerized or otherwise, a good deal of skill can be
required to match the model with the real object.

Anyone who claims to have discovered principles which are beyond those
incorporated in current programs has a heavy burden of proof to bear.
The very first hurdle to overcome in order to gain any semblance of
credibility is comparison of carefully and professionally measured data
with results from a carefully and professionally created model. If the
differences truly are unexplainable by known deficiencies, then further
investigation is surely warranted. Vague claims, speculations, and
arm-waving with a total lack of any quantitative data are far short of
what is needed to gain the attention of anyone who has seen, over and
over, the successful results these programs routinely provide.

so there is a problem. Who would use a digital calculator with
confidence when all calculators are only roughly accurate.
As far as "vague claims" professional programs of today validate my
"speculative" claims. it does not threaten anything of yours since
yours are just number crunchers for pre made designs and even then
they are not totally accurate.
Nobody but nobody has invalidated my expansion of the law of statics.

Computor programs made by professionals do not agree with each other
so there is a problem.

I would suggest that the various codes used by professionals DO agree,
within their stated uncertainty limits or the constraints of the model.

A simple mutual coupling approximation based on series expansion of the
exponential integral for idealized dipoles will be very close to that
derived from, say, a method of moments code like NEC2, but they will be
different, because the underlying model is subtly different. However, a
skilled user of such codes is (or should be) aware of the limitations.

Likewise, you can model a vertical monopole over ground with a simple
model (like assuming the ground is infinitely conducting and the
monopole is infinitely thin). Or you can model it as a finite thickness
monopole and a finite conductivity dielectric ground with uniform
properties. Or, you can model it with the rivet heads holding the
aluminum together, the dielectric guy wires, and the actual EM
properties of the soil that have been determined on a 10cm grid for the
surrounding km.

The answers will all be different in the details, but simultaneously the
answers will be the same within the limits of the approximations used.

The devil is in the details of those limits, eh?

Well you can run around in circles if you think it denotes progress.
If you are really interested in the subject put the same 3 element
antenna
in super nec and 4 nec2 using all dimensions as variable and guess
before hand what result one will give you compared to what the other
one gives you
and ask yourself why with respect to the answer given.
Ofcourse you can say thats not my job and then shoot the messenger.
Do what you think is right. Im doing what I know is right

Art,

You may have missed my earlier message, or perhaps it was not clear. I

Gauss' Law is one of the four standard Maxwell Equations. Therefore,
statics has already been expanded to encompass all of classical
electromagnetism, a long time ago.

You may have invented a novel antenna configuration, but you did not
"invent" the extension of Gauss' Law to HF and antennas. There is
nothing to validate or invalidate.

Pray tell what I have discovered and what antenna program experience
are you drawing upon with respect to your statements. Now to the term
"validated". What does validated mean, is it a collective term? If so
what comprised as a group the term collective? And what in factwere
they validating and how. When and where would help to.
And you seem to be a group of one who recognises what discovery I have
found that it was known about years ago. So why not spit it out and
help out the readers so all know what you are disputing. What I have
uttered has not previously known/understood,even by the maestro Roy
because it is not in any book, and has not been utelised by anybody to
the best of my knoweledge. But you seem to have a handle on the whole
things so with steps of knowelege and logic give all of us the benefit
of your insight so I may advance my case. Again what's your beaf?

Pick up any book that includes a discussion of Maxwell's Equations. One
of the equations will be something like:

div D = rho

The common expression of Gauss' Law is something like:

div E = rho / epsilon

By definition:

D = E * epsilon

Therefore Gauss' Law is already included in all radiation and all
antennas. You can perform any amount of mathematical manipulation you
wish, including expressing these equations in integral rather than
differential form. The integral form is commonly used when discussing
the Gaussian "pillbox" in electrostatics. However, the physical
conditions remain the same.

You have stated on many occasions that you understand this sort of
vector manipulation, e.g., you throw curls around freely, so no further
explanation should be necessary.

I agree and they are correct as far as they have ventured

yes when talking about electrostatics


You have stated on many occasions that you understand this sort of
vector manipulation, This sort?

So am I to assume that you have found a reference to curl by Gauss
specifying its use with respect to electro magnetic fields? Where is
it

So am I to assume that Gauss extended his law on statics to include
electro magnetic fields? Where is that written?

Did he also supply the rational used to arrive at that equation? where
is it written?

e.g., you throw curls around freely, so no further
explanation should be necessary.

You explain what you mean by freely


I don't throw curl around freely but I don't ignor its presence either

where did I throw curl around freely where it wasn't warrented and why
was it not warranted?

Gene you are showing that you are out of your depth, all hand waving

have specifically asked for your facts at each point. If you have them

Well, let's see. I have professional customers who use EZNEC daily to
design complex antennas for commercial, military, and government use. On
many occasions, they test the designs on a test range and find good
correlation between EZNEC and measured results. This has been done over
and over for a wide variety of antennas for years. Countless others have
done the same with NEC and other NEC based programs. I have a standing
request for anyone to report any difference in results between EZNEC and
NEC, and so far have had zero responses except when the user
accidentally made the models different.

On the other hand, I have you weaving your theories but without a single
shred of evidence as far as I can see that the antennas you create have
any advantage over any others, or even that they work as you claim. And
for that matter, I find it nearly impossible to divine exactly what
performance you *are* claiming for your creations.

So, should I check my program for accuracy because of your rambling

Your choice Roy Since you have never had reason to place revisions on
your programs! ( you consider your self as always being right) I see
your point. It has been correct from the get go.
I informed you about the problem in case minninec had some
intertwining with your programs. I am pointing this out because for a
very long time I have been communicating about Gaussian antennas and
from you and others I got howls and ridicule about the whole idea and
the scientific rational behind it.
SO FOR THE MOMENT I bend under pressure from you and your associate
experts to inform you that minninec programs provide evidence of
gaussian arrays.
I have only checked ao and aop for this anomoly that I have been
referring to but I do not have the pocket depth to check all programs
that are connected to NEC. Thus I am alerting you and all nec users
that despite my efforts to show that this is not an error the majority
of experts think otherwise therefore, it would be appropiate for
programmers to see how far this error is embedded if it is an error
and take corrective action.

Just so you don't take your normal aproach when you are out of your
depth I am informing you in the simplest way possible that AO and AOP
which uses a form of NEC produces what I term as a gaussian array if
you allow it to procede without pre direction to a yagi and will
always produce a gaussian array. I am not saying this affects you but
just alerting you since the program has been in existence for many
years when it eminated from the government release of the
underpinnings for the likes of you to copy. If gaussian arrays are in
error according to the majority of this newsgroup as well as
professionals then I suggest that such programs are subject to an
overview that portray that they are legitamate. Programmers and
experts certainly cannot have it both ways and follow the jeering
group as lemmings.Something is wrong and you use this newsgroup to
advertise your product so you cannot avoid the fact that you have been
notified in the future what ever that may be so you cannot say you
were unaware.
Certainly your customers would be comforted with your assurances that
it is not necessary to check.

My point is that Roy is not free from error Jim and you just made my
point.
Over the last few months or even longer I have tried to rationalise
the
correctness of gaussian arrays in early programs .All experts
determined that such a thing is an error. So now I feel that so called
error should be
removed or subject to some sort of over view. As you know minninec was
one of the early programs as well as Annie to come about over thirty
years ago
and later spawned other verions that have no independent oversite. If
the product is incorrect and I am going by Roys newsnet and amateur
group then programmers should be alerted to it. The collection of
experts if we can call them that state there is no connection between
statics and electromagnetics which this derivitation is spawned from.
If they are correct then the program should be corrected and other
programs that spawn from it should also be checked. This problem has
been thoroughly discussed
by many people of this group and they have come to a consensus albiet
as amateurs so shouldn't their words be headed despite what Roy says?

No, I don't have the burden programmers do. Gaussian arrays are part

you recheck your own for accurracy?

Well, let's see. I have professional customers who use EZNEC daily to
design complex antennas for commercial, military, and government use. On
many occasions, they test the designs on a test range and find good
correlation between EZNEC and measured results. This has been done over
and over for a wide variety of antennas for years. Countless others have
done the same with NEC and other NEC based programs. I have a standing
request for anyone to report any difference in results between EZNEC and
NEC, and so far have had zero responses except when the user
accidentally made the models different.

On the other hand, I have you weaving your theories but without a single
shred of evidence as far as I can see that the antennas you create have
any advantage over any others, or even that they work as you claim. And
for that matter, I find it nearly impossible to divine exactly what
performance you *are* claiming for your creations.

So, should I check my program for accuracy because of your rambling
conjectures? Certainly not!

Roy,

You need to learn NOT to rise to the rantings of the para-science
techno-trolls. :-)

Your choice Roy Since you have never had reason to place revisions on
your programs! ( you consider your self as always being right) I see
your point. It has been correct from the get go.

Are you out of your friggin' mind?

The current releases of eznec are 3.0.58 and 4.0.34; sounds like a
revision or two to me.

My point is that Roy is not free from error Jim and you just made my
point.

If there is a point to anything you write it is totally lost in the
rambling, arm waving, and nonsense.

snip rest

You're absolutely right. It's a weakness that I resist but sometimes
succumb to in spite of my efforts. It's time to add Art to my very short
plonk list so I won't waste any more time responding to him.

The sad thing is that I don't believe Art is a troll but rather is
completely serious.

Bye, Art.

May I point out Cecil that when dealing with resonant elements in an
array
which itself is resonant in situ one can then use complex circuitry
methods of analysis for antennas. A case in point is an antenna that
functions as
a pass filter. Sadly the majority resist change especially if it is
seen as self protection. You of all people must be aware that
intolerance by certain people is the reason we have so few
acknoweledged experts left to converse with.If one thinks they have
safety by placing their heads and ears in the sand signifies safety it
is to our advantage if we let them go ahead and do it.
