Adjusting the Computational Domain Size
Specify the computational domain size as follows:
X max = 65 m
Y max = 150 m
Z max = 195 m
X min = 0 m
Y min = -0.005 m
Z min = -164 m
Specify the Symmetry
condition at X max
and X min
.
Specifying Goals
Specify global goals of Max Static Pressure and Max
Velocity.
In addition, specify separate surface goals of Min Static
Pressure at the leeward walls of the buildings.
