Irradiance produced by a plane optical radiation source with complex geometry in any direction - Configuration factor computing with the finite elements method

In order to determine the irradiance produced by an optical radiation source with a complex geometry, a computing code of the configuration factor based on the finite elements method was developed. This paper describes the computation method. Furthermore, the accuracy of the method was tested and the required execution assessed. The computing method was then applied to determine the irradiance produced by an industrial source.
