Finite non-adjacent rectangles



Function  f3d_30(x_1, x_2, y_1, y_2, eta_1, eta_2, z_1, z_2, theta) returns the view factor from area 1 to area  2 of two finite non-adjacent rectangles that are oriented at an angle theta to each other as shown .

Inputs:
x_1, x_2, y_1, y_2, eta_1, eta_2, z_1, y_2 are the lengths shown in the figure [m or ft.]
theta is the angle between the planes [deg or rad]

Example: 
$unitSystem SI deg
x1=0[m]; x2=1[m]
y1=0[m]; y2=1[m]
eta_1=0[m]; eta_2=1  [m] 
z_1=1[m]; z_2=2[m]
theta=45 [deg]
f=f3d_30(X1,x2,y1,y2,eta_1,eta_2,z_1,z_2,theta)   

{Solution: 
F=0.0728}
