Coaxial Finite Parallel Square Planes of Differing Edge Length



Function f3d_20(a, b, c) returns the view factor between two finite parallel squares having the same center.  

Inputs:
a = edge length for square 1 [m or ft]
b = edge length for square 2 [m or ft]
c = distance between squares [m or ft]

Example:  
$UnitSystem SI K Pa J rad
a=0.1 [m]
b=0.2 [m]
c=0.2 [m]
F=f3d_20(a, b, c)

{Solution: F=0.1167} 

f3d_20 calls the more general f3d_14 to do the calculations.
