Point Source Parameters
Variable Type Description Default Value
(Input Group 13c - Building Dimension Data)
SRCNAM character*12 Source name, used to coordinate inputs in Subgroups
b,c,d
HEIGHT real array Array of 36-direction-specific building heights (m) for
flow vectors from 10°-360° in 10° increments
WIDTH real array Array of 36 direction-specific building widths (m) for
flow vectors from 10°-360° in 10° increments
LENGTH* real array Array of 36 direction-specific building lengths (m) for
flow vectors from 10°-360° in 10° increments
XBADJ* real array Array of 36 direction-specific along-flow offset lengths
(m) from the source to the center of the upwind face of
the building for flow vectors from 10°-360° in 10°
increments

YBADJ* real array Array of 36 direction-specific cross-flow offset lengths
(m) from the source to the center of the upwind face of
the building for flow vectors from 10°-360° in 10°
increments

* LENGTH, XBADJ, and YBADJ are required only for the PRIME downwash option (MBDW=2)
The variables in Input Group 13c are entered for each point source for which IDOWN=1 in Input Group
13b. The data for each point source (i.e., source name, 36 widths and 36 heights, 36 lengths, 36 xbadjusts,
and 36 yb-adjusts) is treated as a separate input subgroup and therefore must end with an input
group terminator (i.e., !END!). Once again, the source number is an optional user comment which is
outside of the delimiters. The source name is used to place the building information with the correct
source. The data for each source must follow an opening delimiter and either "WIDTH=" or
"HEIGHT=". The data for each source is followed by a closing delimiter and an input group terminator
(i.e., !END!).
