DHOPT<br />
IPRINT(1)<br />
(1=1, NYEAR)<br />
ITAPE<br />
During heliostat optimization the density and aspect<br />
ratio will be varied by no more than 1 f DHOPT from the<br />
initial values. The larger DHOPT the wider the search<br />
<strong>for</strong> the optimum and the poorer the numerical approximations<br />
used in finding the optimum.<br />
Constraint: 0 < DHOPT 5 0.20<br />
Default: DHOPT = 0.2 (IV . B-2,IV .C-7)<br />
Control parameter <strong>for</strong> zone by zone output of per<strong>for</strong>mance<br />
calculation. The annual zone by zone per<strong>for</strong>mance is<br />
always printed. The average per<strong>for</strong>mance of a user defined<br />
field at all times is always printed. In addition, <strong>for</strong> the<br />
Ith day of the NYEAR days (if IPROB=l or 2 the only day of<br />
the year is 1=1), IPRINT(1)<br />
= 0, no zone by zone output <strong>for</strong> this day;<br />
= 1, daily average printed;<br />
-= 2, each time step and daily average printed.<br />
If IPROR-3 then IPRINT( I)<br />
= 0, no zone by zone per<strong>for</strong>mance printed <strong>for</strong> the I<br />
zenith angle, UEL(1);<br />
= 2, zone by zone per<strong>for</strong>mance printed <strong>for</strong> every<br />
combination of the I solar zenith angle,<br />
UEL(I), and the NIJAZ values of the solar<br />
azimuthal angle (UAZ(1). . .UAZ(NUAZ)).<br />
Default: IPRINT = 9'0<br />
Control parameter <strong>for</strong> reading and writing files<br />
= 0, no reading or writing of files;<br />
= 1, output of per<strong>for</strong>mance run written on local file<br />
Unit 10 <strong>for</strong> use in subsequent design<br />
calculations; this option eliminates need to<br />
duplicate initial per<strong>for</strong>mance calculation <strong>for</strong><br />
different design runs when location and field<br />
options (latitude, dimensions, heliostat<br />
design, etc.) remain unchanged;<br />
= 2, initial per<strong>for</strong>mance input <strong>for</strong> design run read<br />
from local file Unit 20, which should be the file<br />
created on Unit 10 in a previous per<strong>for</strong>mance run<br />
with ITAPE=l; input Namelists FIELD, HSTAT, REC,<br />
NLFLUX, and NLEFF in per<strong>for</strong>mance roup are<br />
omitted with this option (see Table A-Z!.<br />
The user must be sure that the latitude,<br />
insolation model, sunshape, heliostat<br />
design, and receiver/field configuration<br />
read from Unit 20 are those desired in<br />
the present run.<br />
= 3, system input <strong>for</strong> per<strong>for</strong>mance calculation read<br />
from local file Unit 30, which should be the<br />
file created in a design/optimization<br />
