New functionalities for the Tonatiuh ray-tracing software

Tonatiuh is an open source, freeware, Monte Carlo ray tracer suitable for CST applications, and is currently under further development to to increase and improve its functionalities. Work has recently been performed to implement the following functionalities: a flux distribution calculation utility; materials with incidence angle dependent optical properties; and the ability to import 3D geometries from CAD files. This paper provides a detailed account of these new functionalities, and the tests performed to establish their correct implementation in the new software version, Tonatiuh v 2.2.3.
