the j j axis from a minimum of FZMIN meters to a maximum of FZMAX meters,
with respect to the point (XFC, YFC, ZFC).
If IFLAUT=4, the flux points will be automatically located by the code on
the assumed heat absorbing surface of the receiver. For this calculation, the cav-
ity heat absorber height will always be assumed to be that value specified by H
(namelist REC). The default choices for NXFLX, FAZMIN, FAZMAX, NYFLX,
FZMIN, and FZMAX will result in a single point on the center of the north fac-
ing heat absorbing surface. Essentially, for this option the code chooses the “cor-
rect” values of DIAMF, XFC, YFC, ZFC, POLF, and AZMF, and then selects
the appropriate option (IFLAUT=l, 2, or 3) for an external, cavity, or flat plate
receiver, respectively. For this case, as for the first three options, the desired val-
ues for NXFLX, FAZMIN, FAZMAX, NYFLX, FZMIN, and FZMAX should be
specified. Also, if the surface to be examined for fluxes is not on the code-defined
heat absorbing surface (e.g., examining flux at the aperture of a cavity receiver),
then this option cannot be used, and one of the first three options should be used
instead.
II. G-2. Muz Constrained System Designs-Many receiver designs have flux
limitations imposed on the heat absorbing surface to meet lifetime require-
ments. DELSOL provides the option during the optimization procedure to de-
sign systems with a peak flux constraint. The flux at NFLXMX points, where
