Parameter specifying flux calculation. For per<strong>for</strong>mance<br />
runs flux calculations are made at the one time of the<br />
year specified by IFXOUT. For optimization runs, flux<br />
calculations are made only at the design point.<br />
= 0, no flux calculations;<br />
= 1, flux calculations desired.<br />
Constraint: IFLX = 1 if any IFXOUT # 0<br />
Default: IFLX = 0 (II.G,II.F-2)<br />
Parameter allowing selection of the one time of the year<br />
at which the flux is calculated. For the Jth time step<br />
(i.e., (J-1)’HRDEL hours past noon) on the Ith day (I=l at<br />
winter solstice, = (NYEAR + 1)/2 at e uinox, = NYEAR at<br />
summer solstice, as shown in Table 111-4, IFXOUT:<br />
= 0, no flux calculated at this time;<br />
= 1, total flux from user defined field (i.e.,<br />
IUSERF = 1 or 2 in FIELD namelist) calculated<br />
and reported <strong>for</strong> this time;<br />
= -1, flux from every zone printed plus total flux<br />
if IUSERF = 2 at this single time.<br />
Constraint: One IFXOUT # 0 <strong>for</strong> flux maps in<br />
per<strong>for</strong>mance runs, including reruns.<br />
All IFXOUT = 0 if IFLX = 0.<br />
Default: IFXOUT = 144’0 (1I.G)<br />
Parameter specifying the type of surface on which a grid<br />
of flux points will be automatically generated. In all<br />
cases the “center” of the receiver is on the tower<br />
centerline THT meters (Namelist REC) above the plane of<br />
the heliostat pivots (XFC=YFC=ZFC=O). If IFLAUT:<br />
= 1, points are on the outside surface of a cylinder<br />
with a vertical axis. The cylinder has a diameter<br />
of DIAMF meters and is offset by XFC meters to the<br />
east, YFC meters to the north and ZFC meters up<br />
from the “receiver center”. This option with<br />
DIAMF=W (Namelist REC) and XFC=YFC=ZFC=O<br />
generates the flux points on the surface of an external<br />
receiver.<br />
= 2, same as = 1 except the points are on the inside<br />
surface of a hollow vertical cylinder (Figure 11-16).<br />
If RWCAVfl.0, DIAMF must be set by the user to be<br />
W x RWCAV (default is DIAMF=W).<br />
= 3, points are on a plane. The center of the origin<br />
that is used to define the grid of flux points is<br />
XFC meters to the east, YFC meters to the north and<br />
ZFC meters up from the “receiver center”. The<br />
outward surface normal of the plane on the side<br />
that the flux is incident on has an azimuthal angle of
