Titan2d-mod

Titan2d-mod (titan 3.1.1, 2016) is a free open source code to simulate dry granular avalanche flows over natural terrain, modified from an early version (titan 3.0.0, 2011) of TITAN2D code. It is available in the contributor's home page http://lsec.cc.ac.cn/~lyuan/code.html, or searchable in the Sourceforge website.

Overview

The code allows for several variants of the shallow granular flow model,[1] and the governing equations are discretized on Cartesian meshes and solved with the Davis predictor-corrector Godunov type method. The code structures and usage are the same as earlier TITAN2D versions (see user's manual [2]), but some bugs and errors occurring in titan 3.0.0 are corrected, and stopping criteria are added. A non-hydrostatic Savage-Hutter model [3] is implemented as the default.

gollark: I also wondered how you could actually control smart glasses reasonably.
gollark: The temperature here is normal.
gollark: Maybe you can get better lensoforms.
gollark: I consider the sorcerous optics part of the display, but I guess if you can get that working at all it doesn't really matter if you have a higher res one.
gollark: I mean, yes, it can obviously be done, since it has been, I just don't know if it's remotely practical on hobbyist budgets even if you don't mind a low resolution monochrome display.
