Where are the AE911 models?

Senior Member
I have encountered this question asked a few times by debunkers in threads, and it is an important question.

The primary objection to the NIST report is that the data for the computer simulation is not provided. If this information where provided, legitimate questions could be asked, such as, how sensitive is collapse vs non-collapse to changes to the input parameters.
  • So why have AE911, with all their Architects and Engineers, not built an open model based on the available plans?
They clearly have the resources.

Such a model would be of the utmost importance. I would love to experiment with the model, and we can use crowd-sourcing to run thousands of simulations.
  • Surely a "conspiracy theorist" would argue that not providing such a model is evidence of a conspiracy on the part of AE911?
 
While this doesn't directly answer your question, it's worth noting that no scientific research is advanced by obliging other scientists to reverse engineer results in order to verify conclusions. This would only undermine the credibility of the original research. Conclusions are verified by other scientists when they can confirm or falsify results from the original research data, which in this case was paid for by the public.

"So why have AE911, with all their Architects and Engineers, not built an open model based on the available plans?"

Their contention, i believe, is that controlled demolition caused the collapse. If the building was demoed, devices would have had to be placed in specific locations, of which AE911 has no proof of devices having been placed in those specific locations. How does one build an open model based on "it looks like a demo"?
 
Perhaps you misunderstand.

AE911 do contend that fire induced collapse was impossible or very improbable.

The model we require is a dynamic simulation of the building from the plans. The software is out there it just requires a lot of work.

If AE911 are to be believed, there would be extremely few initial conditions (if any) that would lead to collapse.

I have even seen it threatened by skeptics that one day we will have these models and then everyone can see the truth.

So, AE911, make one for us. It would really help us all converge on the truth.

This shows a hypothetical 8.755" displacement towards the west. This proves only that the girder is strong enough to stay on the seat, if the stiffeners were faithfully modeled and there was no girder axial expansion.

What it doesn't show is the heating, which would drive the girder up against the face of C79, just like NIST said would happen in the Finite Element Analysis of the Northeast Floor Framing System--NCSTAR 1-9, page 352, PDF page 396.

The girder could never push more than about 3.5". For crying out loud, if the beams are expanding, so is the girder!

Is heating of the girder by fire involved in the NIST real-world or is this just an exercise?

On page 351, PDF page 395 it says, "For column 79, the flange on the north face and the extending portions of the side cover plates were modeled to allow for contact with the girder."

On page 354, PDF page 398, Figure 8-26 shows the girder up against the west side plate.

Any questions?
 
NIST are not working on this any more, as far as I know.

Can you explain why you won't release any of the models you have done?

For now, but if they were doing their job properly they would be revisiting it.

Surely someone who trusts NIST words so much would realise that to release such information could potentially jeopardise public safety.;).
The fact of the matter is that these are done by a highly skilled engineer who designs daily. You should really be asking NIST why they are so afraid to release their input data and allow it to be checked.

I'm asking you. You know NIST's answer and you disagree with it, so what's your (serious) answer?
 
I do not have a clue what NISTs answer is and neither does anyone else outside of NIST. That's the problem. They have never considered the connection with the correct elements present. The FEA above does.

You must have misunderstood what I was saying, because I was referring to your statement "You should really be asking NIST why they are so afraid to release their input data and allow it to be checked." You know full well the reason that was given for not releasing it, seeing as you just quoted it two sentences earlier.

I'm asking what your reason is.
 
If the data that NIST is withholding is an issue of national security, and gerrycan (etc) releases what would essentially be that data, he can face imprisonment.
Besides, NIST made the initial claim. The burden is on them. But they can avoid ANY burden by claiming it's an issue of 'national security.' It's such a joke.

Look above. gerry is making a claim, but he's keeping his model secret. Are you really going to say "NIST won't, so why should gerry?"
 
Umm yeah. They made their claim first. Burden of proof? Buried in secrecy.

I think it's more of a, you show me yours I'll show you mine deal...

That makes no sense at all. If Gerry has evidence of a cover-up involving the murder of thousands of people, you think it's valid to play silly games?

What is the downside of releasing his model?

That is a massive accusation to level at someone in a public forum who is arguing about a building in whose collapse nobody allegedly died. I request you withdraw that right away. I have a serious objection to what you just said here Mick.
 
Surely though that's the implication of your research:
  • WTC7 could not have collapsed from fire alone
  • hence it was premeditated demolition
  • hence the people who did it were aware that the planes would hit the towers
  • hence they were involved with the destruction of WTC 1&2
  • And the NIST report seems to have serious, possibly deliberate omissions, so NIST were in on the conspiracy.
Should I just say "evidence that suggests ...."
 
You can make those leaps if you like. I prefer to take things one at a time. The ONLY thing I have ever spoken about on here are errors and omissions in NISTs report. I think it should be re-investigated, and I do not presume to know what a fair and honest investigation would conclude. I certainly would not go around accusing people of being accessories after the fact, I would rather wait to see what the outcome of a proper investigation would be, rather than making huge accusations against people out of frustration.

It still falls on NIST. Burden of proof my friend. Does that disappear when NIST is involved? You can say whatever pleases your heart to shift the burden of proof but at the end of the day, that falls on NIST.
And YOU'RE making the implications here. Not gerrycan.

I'm sorry, but I don't see what other conclusion can be reached from your claims about NIST's report. You've basically accused them of covering something up.

Or do you just think that WTC7 fell due to fire, but in a slightly different way than they suggested?

Or is there some middle way I'm missing here?

That's entirely not the point. I want NIST to release their data. I want Gerry to release his data.

So why should Gerry not?
 
For crying out loud, if the beams are expanding, so is the girder!
And so were the beams and flooring on the other side of the column.

And the column was also expanding upwards from beneath.

And if the fire was progressing (as it obviously was) then there would also have been a moving lateral displacement of the column, caused by the wandering temperature gradients, threatening its compression stability by taking the column center of the vertical, and making nonsense of any single particular beam or girder expansion limit analysis.

No, I have not accused NIST of covering anything up. Errors and omissions. The middle way that you are missing here is to investigate it thoroughly, without preconceived ideas of the outcome. I prefer to remain objective rather than to draw conclusions at the outset, as NIST did in the case of WTC7.

So why don't you make a compelling case for that, by illustrating their errors by releasing your own, more accurate, model?

You should refer your questions re ae911truth and their FEA model or lack thereof to them, not me. You are the guy with the modelling experience as you stated earlier. Why not do your own?

Gerry, you just posted a rendering of model. Where did that model come from?

Why should he put himself at risk of becoming another Snowden or Manning when NIST have given the reason of National Security. You should be careful about the things you ask people to do.

You should also be careful what you accuse people of in an open public forum. I note that you still haven't removed this baseless accusation despite my requests that you do so.

I have explained it.

What about your models? Can you at least explain what the deal is there? You did them at work, and you are worried your name would be in the metadata? What?

Seriously Mick, are you trying to provoke me here? Let's have this debate in an open forum that is a level playing field, and that way we can both speak our minds openly. I told you that these models were done by a highly qualified engineer who designs stuff every day. If that's not good enough for you, go and make your own model. You are after all, as you said earlier, experienced in the field of computer design. In the meantime, you don't know who made this model, and i am certainly not going to tell you.

The point is, based on your own arguments, the model is worthless without verification. It could have been done in photoshop.

What I'm asking is WHY can't you release the model? Surely that's a very simple question?

I don't have experience with FEA. My experience with models comes from the video game industry. The scale is similar, but the requirements are different. When I was doing it we rarely had physically deformable meshes, and the physics simulation treated everything is rigid bodies, and mostly immovable. I have some experience with things like verlet integration and fluid dynamics. Here's a couple of articles I wrote:

http://cowboyprogramming.com/2007/01/05/blob-physics/
http://cowboyprogramming.com/2008/04/01/practical-fluid-mechanics/

I might have a go at doing some models, unfortunately, knowing me, it will probably take a year or so, and not be particularly helpful.

The sensible thing would seem to be the original suggestion - some kind of open source attempt, where hundreds of people can collaborate on building and verify a model.

Can you explain why the model you displayed above could not be part of that?
