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