These simulations represent part of the output from the high-amplitude folding program described in the following reference:
Cruikshank, K.M. & Johnson, A.M. 1993. High-amplitude folding of linear-viscous multilayers. Journal of Structural Geology, 15(1):79-94.
The display programs on this page are now out-of-date enough that some of teh common tecnology 20 years ago is not readily available. I am working on revised versions that will work with modern graphics.
The programs work from the command line (e.g.animate layer-10.ffb), however you will be prompted for a filename if yo do not provide one on the command line.
The graphics is somewhat crude, but it does allow you to see what is going on.
This set of programs creates plot files in a variety of formats from the animation files.
