Number of zone divisions azimuthally around the tower.<br />
Constraint: NAZM 5 12; NAZM, even.<br />
Default: NAZM = 12 (II.B-l,II.B-2,II.F-6)<br />
Number of zone divisions in the radial direction from the<br />
tower.<br />
Constraint: NRAD = 5 13 (1I.B-1 ,II.B-2,1I.F-6)<br />
Default: NRAD = 12<br />
Minimum and maximum radial position of heliostats, expressed<br />
in normalized units of distance based on the tower<br />
height, THT (REC namelist).<br />
Default: RADMIN = 0.75<br />
RADMAX -= 7.5 (11. B- 1 ,IV .C-6)<br />
Control parameter <strong>for</strong> surround vs. north-only field (used<br />
primarily in small systems)<br />
= 0, Surround field with equally spaced azimuthal zones<br />
surrounding the tower;<br />
= 1, Finer zoning of the north part of the field set<br />
by AMAXN.<br />
Constraint: If INORTH = 1, IREC > 0<br />
NUMCAV = 1<br />
RAZM(1) = 180.0<br />
in namelist REC.<br />
Default: INORTH = 0 (1I.B-1)<br />
Maximum angle, in degrees, from north-south axis <strong>for</strong><br />
north field zoning option (INORTH = 1). There are (NAZM-1)<br />
zones from -AMAXN to +AMAXN(") about the north-south<br />
axis; remaining zone is a "dummy" <strong>for</strong> the south part of the field.<br />
Constraint: INORTH = 1<br />
Default: AMAXN = 82.5(") (I1 .B- 1 ,II. B-2)<br />
Control parameter <strong>for</strong> heliostat layout pattern:<br />
= 0, radial stagger (only option at present)<br />
Default: ILAY = 0 (1I.C)<br />
Parameter specifying heliostat density; options 1, 2 and 4 based<br />
on U. of Houston results:<br />
= 1, high reflectivity (-0.9 rectangular heliostats;<br />
= 2, low reflectivity (- 0.6 1 round heliostats;<br />
= 3, user specified (see below).<br />
= 4, 1984 cost data base, updated shading/blocking<br />
Default: IDENS = 1 (1I.CJV.B-1,IV.B-2)<br />
Parameter specifying field option <strong>for</strong> initial per<strong>for</strong>mance<br />
