WTC 7 collapse simulation data

400 Gigabytes for $227.98. Looking for someone who understands the ANSYS I/O format to determine if this is worth it.

Dear Mr. Ri tchey,
This letter is in response to your February 4, 2008, Freedom of Information Act (FOIA) #09-48 request to the National Institute of Standards and Technology (NIST) in which you requested a copy of "Case B input and output from the ANSYS analysis as described on page 35 ofNCSTAR lA, The Final Report on the Collapse of World Trade Center Building 7."
As previously determined, you are in the "all others" category, for which chargeable services include search and duplication of responsive documents excluding the cost of the first 2 hours of search and the first 100 pages of duplication. We initially estimate this cost to be $227.98. This estimate is based on the duplication of the input and output files for the analysis, which is approximately four hundred (400) gigabytes of information. The most effective way of providing this voluminous amount of files would be to place them onto a computer hardrive. Upon receipt of your written assurance to pay the $227.98, we will begin the duplication of responsive files. Written assurance may be provided either by letter or email
to Since this is just an estimate, if the actual cost for the duplication ofresponsive files is more than this estimate, then we will notify you of the revised charges. Likewise, if the actual cost for the duplication of responsive files is less than the estimate, you will be required to pay less.
Please be advised that the search charges are assessed whether or not responsive documents are located
and whether or not any of these documents are exempt from disclosure under FOIA.
If we do not receive written assurance from you within thirty calendar days from the date of this letter, we \ovill assume you are no longer interested in receiving the documents requested and your FOIA request will be closed. Our mailing address is: NIST FOIA Office, 100 Bureau Drive, MS 171 0, Gaithersburg, MD 20899-1710.

This is a different data set than the LS-DYNA FOIA:

ANSYS was used to model "structural response of the lower 16 stories of WTC 7 to the heating from the fires on Floors 7 through 9 and 11 through 13" which was then fed into the LS-DYNA models.


We will get send the check and release the data as soon as it arrives. Thanks to everyone who donated! -jk
