Detailed Description

Computes view factors according to the double line integral (2LI) method.

Usage

Minimal example in <constant>/viewFactorsDict:

// Optional entries
alpha    <scalar>;

// Inherited entries
...

where the entries mean:

Property	Description	Type	Reqd	Deflt
alpha	Perturbation for common edges	scalar	no	0.21
