Disk to coaxial cone.
Function F3D_63(r_1,r_2,alpha,s) returns the view factor between a disk and a concentric cone.
Inputs:
r_1 = radius of disk [m] or [ft]
r_2 = base radius of cone [m] or [ft]
alpha = angle of cone [radian] or [degree]
s = distance between disk and tip of cone [m] or [ft]
Example:
$UnitSystem SI Mass J K Pa Radian
r_1=0.2 [m]
r_2=1 [m]
alpha=pi/4 [radian]
s=0.1 [m]
F=F3D_63(r_1,r_2,alpha,s)
{F = 0.4584}
