I maintain a set of free downloadable files which includes source code for 6 different finite-element programs that may be useful to geologists, geophysicists, and tectonophysicists. Associated graphical programs and sample input and output files are included.
In previous years, these files were offered from an FTP server at the URL of ftp://element.ess.ucla.edu. However, in 2007 this material was moved to the present web site at URL of http://PeterBird.name, where FTP service is not available.
UNFORTUNATELY, this new way of serving files has a major disadvantage: The current HTTP server (Microsoft IIS 6) will only serve files whose names include a “known extension.” The list of known extensions is rather short; those relevant on this web site are: .ai, .bas, .bin, .doc, .exe, .gif, .jpg, .mid, .mp3, .pdf, .txt, .xls., & .zip. The server does NOT recognize many other long-standing extensions found on files that I wish to serve to you, such as: .bat, .bi, .for, .f90, .mak, .nwc, .qlb, & .sib. Naturally, it does not recognize the filename extensions that I have created within my own suite of programs: .bcs, .dat, .dig, .eqc, .feg, .gps, .grd, .in, .mod, & .out. In every case, my work-around has been to add an extra .txt extension, e.g.: Slippery.f90 becomes Slippery.f90.txt which will allow you to view the Fortran 90 code as text and download it as text. IN ALL CASES WHERE YOU DOWNLOAD FILES WITH TWO EXTENSIONS, THE SECOND EXTENSION OF .txt SHOULD BE REMOVED BY RENAMING THE FILE IMMEDIATELY AFTER DOWNLOADING. (Otherwise, the filenames will not match those in my documentation files.)
Now, there are two alternate ways to access these files:
(1) Download the whole FTP archive, in whole_FTP_archive.ZIP. Un-zip this into a new folder on your own computer. Then, browse through it and discard whatever you don’t want.
(2) Enter the tree of folders at http://peterbird.name/oldFTP/ and navigate to the file(s) you want. Download each file that you want individually. (In Windows Internet Explorer, you would right-click on a file and select “Save Target As...”.) There is no way to download an entire folder with one command; but, see method (1) above.
For an overview outline of the available files, see "oldFTP_READ_ME.txt ", which is plain ASCII text.
The codes that you can obtain here are mostly in Fortran77 and Fortran90, and you can compile them yourself for computer systems other than Windows (such as Unix, Linux, or MacOS). Treat these files as ASCII text. However, the Shells and NeoKinema families of programs (in folders /neotec/Shells/ and /NeoKinema/ , repectively) include complete sets of .exe files compiled for Intel-family processors (e.g., Pentium) running 32-bit Windows (Windows 95, Windows 98, Windows ME, Windows NT, Windows 2000, Windows XP, Windows Vista, etc.). You should download any .exe files as binary data, and place them on a Windows computer for use. I am gradually adding executables compiled for 64-bit Windows (Windows 7, 8, 10, ...) and marking these files with names that end in -Win64.exe.
If you want to know what these programs do, and how they differ, a good
starting point is my review paper:

" If you are looking for the Lost Frontier, talk to us. "
Many of us are descended from pioneers: maybe from those early humans who migrated out of Africa, or the ones who chose to come settle in the New World. Or, maybe we just left our relatives on the east coast and moved to California. It's no surprise that we feel unsatisfied in a modern world that often seems completely fenced, civilized, and full of people. (A national park experience is nice, but after you wait 6 months for a reservation, and read the two pages of rules, it doesn't seem very wild.) Here in Earth & Space Sciences we know some routes back to the edge of the unknown. We can set you up with a mapping project in the deserts of Asia, South America, or Mexico. We can train you to design and operate satellites that map the other planets and moons of our solar system. Or, we can teach you how (with a little tectonics, some stratigraphy, and some paleobiology) you can travel the most crowded landscapes and "see" them as they were in the Cretaceous. There's a lot of elbow room along the fourth axis of space-time.
" Science is the ultimate MMORPG. "
(MMORPG = Massively Multiplayer Online Role-Playing Game, like Everquest or World of Warcraft.) It's online because that's where we search for literature, read e-journals, browse each others' Web pages, and download each others' data sets. It's role-playing because we must pretend to be logical, impartial, patient, and modest, even if most of us are quite different in person. It's a game --not a contest or a war-- because the total amount of goodness is increased by the playing. If you discover something, it doesn't hurt me. And if you tell me about it, we both benefit.
Now, to reward your patience in reading this far down,
I am pleased to share with you the
Ultimate Answer to the Ultimate Question of Continental Drift, Seafloor Spreading, Earthquakes, Volcanoes, and Everything!
(full-size image) [Bird et al., 2008, JGR]
Despite what you may have heard elsewhere, the answer is not "42." There are actually at least 52 plates on Earth [Bird, 2003, G3].
