<DIV><FONT face=Arial size=2>I encountered the same need when I
was providing technical assistance on building energy standards for
Egypt back in 2003. A visiting Egyptian researcher said they needed to model
buildings with dones, which were prevalent in both religious (mosques) and
commercial buildings. So, I wrote an awk script that generated DOE-2.1E input
based on the input dome diameter and the specified number of arc segments
(horizontal rows) desired. The script generates produces a series of
polygons to model the dome in any detail. Caveats are : (1) the dome
is hemispherical, (2) the model of course does nothing about air stratification
or other thermal effects, (3) one can easily be entranced by the
representational accuracy of the script and transform the dome to hundreds of
poygon - clearly geometrical overkill - but it looks good in
drawings.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The description of the procedure is
descrubed in an article I wrote in the Sept/Oct 2002
issue of the USER NEWS, "Adapting DOE-2 to meet the needs of the
Egyptian Housing and Building Research Center", p. 18-19. You can get to
the article on <A
href="http://gundog.lbl.gov/dirun/23s_o_1.pdf">http://gundog.lbl.gov/dirun/23s_o_1.pdf</A> .
It includes the awk script and a sample input.</FONT></DIV>
