THE FEMCI BOOK*
Welcome to the heart of FEMCI online. The Book is an online library of useful information regarding finite element analysis, such as How-To's and engineering theory.
Additional information can be found through presentations given during FEMCI meetings. Visit the Presentations page.
If you are a NASA civil servant or one of our contractors and wish to contribute to the Book, then please send your work to us for consideration at FEMCI@mscmail.gsfc.nasa.gov.
(We're sorry, but we cannot consider unsolicited works unless you are a NASA civil servant or directly associated with NASA.)

* We have received a few requests for a "copy" of the FEMCI Book. You're reading it! There is no physical book, but rather this web page. It started out originally as a three-ring binder "book" but was made 100% electronic with the creation of the FEMCI website.
