Control parameter <strong>for</strong> optimizing the heliostat densities.<br />
= 0, no heliostat density optimization. The “default” densities<br />
(which are a function of the tower height) are used.<br />
The heliostat field boundaries are optimized;<br />
= 1, heliostat densities are optimized.<br />
Constraint: Tower height cannot be varied if IHOPT = 1.<br />
Default: IHOPT = 0 (II.C,IV.B,IV.C-7)<br />
In optimization run, NUMTHT discrete, equally spaced<br />
values of the tower height are tested from THTST to THTEND<br />
(in meters). If NUMTHT = 1, then the tower height is<br />
set equal to THT specified in the REC namelist; THTST and<br />
THTEND need not be specified.<br />
Constraints: THTST 5 THTEND<br />
1 5 NUMTHT 5 20<br />
Default: NUMTHT = 1<br />
THTST = 75.0 (m)<br />
THTEND = 400.0 (m) (1V.C-2,1V.E)<br />
External receivers (IREC = 0 in REC namelist): NUMREC<br />
discrete, equally spaced values of the diameter tested<br />
from WST to WEND (in meters). If NUMREC = 1, the only<br />
value of the diameter considered is that defined by W in<br />
the REC namelist.<br />
Cavity (IREC = 1, 2) and Flat Plate (IREC = 3,d)<br />
Receivers: NUMREC discrete, equally spaced values of<br />
the horizontal dimension of the first aperture or flat<br />
plate, RX(l), tested from WST to WEND (in meters). If<br />
NUMREC = 1, the only value considered is that defined<br />
<strong>for</strong> RX(1) in the REC namelist.<br />
Constraints: WST 5 WEND<br />

Default: NUMREC = 1<br />

WEND = 26.0 (m) (1V.C-3 ,IV.E)<br />
Ezternal receivers (IOPTUM = 1): NUMHTW e ually spaced<br />
values of the receiver height to diameter ratio (HTW)<br />
tested from HTWST to HTWEND. If NUMHTW = 1, only the<br />
ratio defined by H and W in namelist REC is used.<br />
Cavity and flat plate receivers (IOPTUM = 1): NUMHTW<br />
equally spaced values of the ratio of the height to<br />
width, RY(l)/RX(l), of the first cavity or flat plate<br />
tested from HTWST to HTWEND. If NUMHTW = 1, only the<br />
ratio defined by RX(1) and RY(1) on Namelist REC is<br />
used. The width W is held constant.<br />
Cavity receivers (IOPTUM = 2): NUMHTW equally spaced<br />
values of W tested from HTWST to HTWEND. If NUMHTW = 1,<br />
only the W defined by namelist REC is used. The aspect<br />
