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}
