This file is then input into FDS using a command like this:
fds > townhouse2.data
FDS creates all files needed by smokeview. To run smokeview,
type: smokeview townhouse2.smv
Smokeview is now running and the menus may be accessed by right
clicking in the window. Smokeview as written by Glenn Forney uses the GLUT window
and menu system. GLUT is designed to get OpenGL programs running quickly without
too much complication. When the townhouse
is loaded an image like this will appear:
Using the menu, different file data on the townhouse may be visualized. Here, the "mixture-fraction" file was selected, showing the fire and smoke propagation and nothing else. In the screenshot on the main page, the "boundary temp" file was selected in addition to this, so the temperaures on the surfaces may be viewed along with the fire and smoke propagation. This is an extremely brief introduction in the basic use of smokeveiw. Fot more information, including downloads of smokeview, documentation and all other information one could possibly want, please visit NIST's smokeview website:
Here are some short Quicktime videos of the townhouse fire, with and without the boundary temperatures displayed. Unfortunately, the SGI Octane that I was capturing these films on was hiccupping and dropped a number of frames so the motion in these videos is quite jerky. As soon as I figure out why this was happening, I will post new smoother videos.
