/neotec/ is short for "neotectonics" (ongoing and/or Quaternary)
as opposed to folder names /paleotec/ (for "paleotectonics,"
e.g., Late Cretaceous-present Laramide orogeny simulations) and
/Restore/ (for kinematic palinspastic restoration sequences).
The difference is that neotectonic programs only compute velocities
(and strain-rates and stresses and torques), but not finite 
displacements.  Thus, they do not step through geologic time,
nor do they compute finite strain over time, or change the
thicknesses of crust and mantle lithosphere.

Most visitors who come here will probably want the contents of 
                /oldFTP/neotec/SHELLS/
which contains our latest thin-spherical-shell neotectonic 
DYNAMIC modeling program.  If you plan to work with Shells,
you will also want the contents of these related folders that
are NOT located within /oldFTP/neotec/:
/oldFTP/OrbWin/    = latest version of our grid-editor program.
/oldFTP/PB2002/    = 52-plate rigid-plate kinematic model, with some files
                     that Shells will need to assign boundary conditions
                    (for certain BC type codes) and/or to assign nodes to plates
                     for purposes of computing torque balances on each plate.
/oldFTP/FiniteMap/ = latest version of graphics (mapping) program.

If you want to do KINEMATIC neotectonic modeling (fitting velocity fields
to primary data, not worrying about rheology and stress-equilibrium), then
see these folders:
/oldFTP/OrbWin/    = latest version of our grid-editor program.
/oldFTP/NeoKinema  = weighted-least-squares fit of velocity field to data.
/oldFTP/NeoKineMap = graphics (mapping) program for NeoKinema files.
/oldFTP/Long_Term_Seismicity = convert NeoKinema and/or PB2002 and/or
                               Shells (intraplate) velocity fields to 
                               SHIFT forecasts of long-term seismicity.

The other folders found here in /oldFTP/neotec/ include:

/oldFTP/neotec/Digitise/ = Utility program (for DOS/Windows) that accepts
                          (x,y) points from a digitiser through an RS-232 serial port,
                           and saves the results in .dig file format.
                           Written in Microsoft BASIC; this compiler had no upgrade path!
                          (Few people do their own digitising by hand anymore.
                           It is more likely that you will re-format some digital
                           data into our .dig format with a utility program that
                           you write in your own preferred language.  If so, see
                           the documentation of .dig file format at:
                           http://peterbird.name/guide/dig_format.htm

/oldFTP/neotec/DrawGrid/ = Interactive editor for small 2-D F-E grids in flat-Earth (x,y)
                           coordinates (as needed for dynamic F-E programs PLATES & FAULTS).
                           Executable DRAWGRID.exe runs under DOS or Windows.
                           Written in Microsoft BASIC; this compiler had no upgrade path!

/oldFTP/neotec/FAULTS/ = Neotectonic, dynamic F-E program FAULTS, whose domain is the crust
                        (only) in a flat-Earth, 2-D geometry.  Basal boundary conditions
                         representing velocities of the Moho can be included.
                         Used in Bird, P. and X. Kong (1994) 
                        "Computer simulations of California tectonics 
                         confirm very low strength of major faults," 
                         Geol. Soc. Am. Bull., 106 (2), 159-174.

/oldFTP/neotec/Forearc = Utility program to assign lithospheric thickness and other
                         nodal data along one margin of a Shells F-E grid, in cases
                         where the Shells model will include the overriding plate
                         of a subduction zone, but will not include the subducting
                         plate.

/oldFTP/neotec/PLATES/ = Neotectonic, dynamic F-E program PLATES, whose domain is the 
                         entire lithosphere, in a flat-Earth, 2-D geometry.
                        (Note that crust and mantle lithosphere are assumed to move
                         together; if you want to model independent motion, see program
                         LARAMY in /oldFTP/paleotec/.)

                         Alaskan neotectonics," Tectonics, 15, 225-236.
