Perpendicular Rectangles with no Common Points
Function F3D_13(a1, a2, b1, b2, c1, c2, c3) returns the view factor from area 1 to area 2 of two finite rectangles that are oriented perpendicular to each other and having no common points.
Inputs:
a1, a2, b1, b2, c1, c2, and c3 are the lengths shown in the figure in [m or ft]
Note: The input values must all be greater than 0!
Example:
$UnitSystem SI K Pa J deg
a1=0.1 [m]
a2=0.2 [m]
b1=0.5 [m]
b2=0.5 [m]
c1=0.5 [m]
c2=0.05 [m]
c3=0.5 [m]
F=F3D_13(a1, a2, b1, b2, c1, c2, c3)
{Solution: F=0.01626}
