Creative Speculation

... did not include the rigid shell of exterior curtain walls because they were not considered to be structural members and therefore were not a factor in the collapse. They were, however, apparently rigid enough to hold their box shape when the interior support columns and beams collapsed. Without those curtain walls included in the model, there is no reason to expect the model to LOOK like the actual collapse. But that's an entirely superficial and perfectly pointless observation, and it seems you make in order to distract attention from important points where the NIST model does indeed bear more than a "resemblance to reality" such as the collapse of the penthouse:

> The collapse of the e. penthouse could easily have been achieved simply by cutting the floor beams on the 46th floor.

LOL, and just WHY would "they" do that, pray tell? And while you're at it, how about an explanation for why "they" would blow out columns on eight floors AFTER the building was already falling?
